How can you cope with a cancer diagnosis?

D
espite cancer being one of the most prevalent diseases in the world, receiving a diagnosis still comes as a shock. In this article, we offer advice from both healthcare specialists and those who went through cancer on how to cope with this diagnosis.

We spoke to healthcare professionals and gathered online resources to support you in your pursuit of well-being and coping with cancer.
According to the World Health Organization (WHO), cancer is one of the most widespreaddiseases worldwide. The National Cancer Institute (NCI) estimate that, in the United States alone, there were approximately 1,685,210 new cases of cancer in 2016.
What are some practical ways that could help you to cope with the shock of a cancer diagnosis, and allow you to make the best decisions for yourself?
Medical News Today have spoken with healthcare professionals and explored the experiences of people living with cancer with the aim of bringing you advice on how to face this unwelcome news.

'Make sure you understand your diagnosis'

Getting diagnosed with cancer comes as a shock to anyone, but one important way of coping with it is to be well informed. Cancer is often surrounded by an aura of myth, and much of what we think we know about it can be based on hearsay.
So, an important first step is to get as much (specific) information as possible, from both your doctor and other reliable sources.
Dany Bell — a specialist advisor on treatment and recovery at Macmillan Cancer Support, based in the United Kingdom — told MNT, "Being diagnosed with cancer can be a big shock, even if you already suspected you might have it."
"Cancer is a word that can stir up many fears and emotions," adds Bell, "but making sure you fully understand your diagnosis can help you feel more in control of the situation."
The NCI also list a set of suggested questions that you can ask your doctor about your diagnosis.
In a vlog about her experience living with stage four ovarian cancer, Texas-based Sharon Nancespoke about how staying informed helped her to cope with this news.
"If you ever find yourself faced with a cancer diagnosis [...] [b]efore you go into a panic mode, I say take a deep breath, be calm, gather as much information as you can about what type of cancer you're dealing with, what the odds are for the type of cancer that you have, and then go from there, because if you know what you're dealing with, it's not so frightful."

Speaking to your doctor

Often, communication with your physician might feel tricky, since the subject of a cancer diagnosis is always a heavily loaded one. Both you and your healthcare provider might find it difficult to communicate efficiently.
Dr. Ann O'Mara — head of Palliative Care Research in the NCI's Division of Cancer Prevention — told MNT that there is no magical recipe for success in these cases, but that open communication is very important to ensure that you get the information you need, and that your physician knows how you are coping with your diagnosis.

"If the communication with that physician is causing you to be more stressed out you have to communicate that to the physician," she said.
"Patients have to [...] communicate to physicians if they're not getting the right information, or if the information is really devastating to them, they have to be open [with] their physician," Dr. O'Mara emphasized.
The NCI also offer detailed advice on how to approach your healthcare team in order to ensure the best and most effective communication with them.

Talk about it

Symptoms of depression and anxiety are often a natural outcome after a cancer diagnosis. After all, there are so many unknowns to this equation, and this is a journey that will undoubtedly turn your life upside down.
That is also why it's so important to be able to count on a strong support network.

Approaching friends and family

Bell told MNT that being able to rely on a good support network is always helpful, even though speaking to the people around you about your diagnosis may be a challenge all on its own.
"Telling friends and family you have cancer can be daunting, but many people find that having a good support network around them really helps. You may want to tell those closest to you first. After this, you might find it helpful to make a list of who you want to tell. If you like, you can ask someone you trust to tell people for you."
Dany Bell
"Before telling someone you have cancer," Bell added, "think about what details you want them to know. Writing this down might help."
earnest conversation
Although you may find this difficult to begin with, speaking to friends and family about your diagnosis can help.
Dr. O'Mara agreed that it's important to talk about your diagnosis with your nearest and dearest. It may be helpful, she noted, to "start with [your] family, and then with friends." She also suggested that some might find it easier to tell just one friend to begin with.
"You tell one friend, you tell your closest, your best friend, and you ask them to be [...] the sounding board for you, so you're not spending all of the time on the phone talking to everybody," she said to MNT.
Additionally, the physical context in which you talk to others about your diagnosis is also important, Bell pointed out.
"Choose a time and place where you'll have time to talk without being interrupted," she advised. "Try to be honest about what you know — it's O.K. to say if you are unsure about anything, or can't answer all their questions."

Asking for help

Dr. O'Mara also told MNT that it may be hard for individuals newly diagnosed with cancer to solicit support, even though they may find that friends shower them with offers of assistance.
She suggested to ask for specific, pragmatic help with small things, such as a lift to your next medical appointment, or a cooked meal. Small, targeted actions can go a long way.
"When people come to you and say 'how can I help you,' the thing that you can do is give them a task, ask them to do something [specific], [...] ask them to make a meal for you," said Dr. O'Mara.

Finding a dedicated support network

You may also find it helpful to locate a dedicated support group online, or in your own community. There are many kinds of cancer support groups, which you may be able to trace through online searches or by speaking to the specialist by whom you were diagnosed.
Dr. O'Mara explained for MNT that you should easily be able to find a support group just by asking your healthcare provider.
"In most of our cancer centers," she said, "and even in our local physicians' offices, any experienced clinicians [...] — doctors, nurses, nurse practitioners etc. — usually have a list of local support groups. Oftentimes the hospitals run them for newly diagnosed cancer patients and their families."
Still, as U.K.-based Dr. Liz O'Riordan — a consultant oncoplastic breast surgeon who has experienced breast cancer — notes, online support networks should not be discounted either.
In her TED talk, she speaks about how she unexpectedly found much-needed emotional, as well as practical, support through social media.
Dr. O'Riordan explains that she "got her own secret tribe" by using Twitter, which helped her to find other healthcare professionals who had been diagnosed with a form of cancer and were about to undergo treatment.
Being able to talk to people who were, or had been, in a similar situation to her was a valuable self-care resource, she says in her talk.

Use anger and grief as a 'lever'

Responses of grief and anger are normal feelings to experience when receiving a cancer diagnosis, but such emotions need not be destructive.
The NCI say that, in addition to discussing your feelings with healthcare professionals and your trusted support group, it may help to keep a journal and write down your feelings, in order to fully process them.
In a vlog, Nance said that these negative emotions can sometimes be used for leverage. For instance, anger helped her to understand that she didn't want cancer to take hold of her entire life.
"You have every right to get angry, and I almost encourage that you get angry because it is that fire that's going to make you get up and say 'you know what, O.K., I've got cancer, but I [will not] continue to dwell on the negative aspects of this disease anymore.' And that's what I had to ultimately do."
Sharon Nance

Don't let cancer take over your life

"You have cancer, but don't let it have you," added Nance.
Cancer may be in your body and affecting the way that you live your life, but continuing some old activities that you took pleasure in, or taking up something new, such as crafting, drawing, or writing, could help you to stay in touch with who you are outside of your health profile.

If you can, keep doing some of your favorite activities, or pick up a new hobby, to help you focus on something other than your diagnosis.
The NCI suggest "looking for things you enjoy" and shifting more of your mental and emotional focus onto something pleasant and creative. Some gentle exercise, they say, might also prove useful.
On her blog, Dr. O'Riordan also notes that even though the least taxing physical activity may be exhausting — especially if you're going through chemotherapy — this could help you to cope.
"The best thing you can do is to do a little bit of exercise every day. [...] I hated getting ready to go out but felt so much better for it, and felt I'd earned the right to veg out on the sofa for the rest of the day," she says.
Nance candidly explained that "it is a work in progress to learn to live with cancer." There is no right or wrong way of coping, and what is essential is that you stay in charge of your body and your life.

These 5 tropical plants may 'provide anticancer benefits'


I
n a recent study, scientists identified several tropical plants that have anticancer properties.
bandicoot berry
The Bandicoot Berry (shown here) may have anticancer benefits.
Researchers from the National University of Singapore, Department of Pharmacy (NUS Pharmacy) spent 3 years investigating the pharmacological properties of local plants.
They found that three species were particularly effective at inhibiting the growth of several cancers, and they have now published their findings in the Journal of Ethnopharmacology.
Despite the widespread use of modern medicine in Singapore, there is a tradition of using local plants to treat various conditions, including cancer.
Cancer is the current leading cause of death in Singapore, where 1 out of every 4–5 people develop the condition at some point in their lives.
2017 report by Singapore's Health Promotion Board stated that the number of people who receive a cancer diagnosis will continue to rise, but that the number of people who survive will also increase as medical technology and cancer care improve.
Southeast Asian countries, including Singapore and Malaysia, are undergoing rapid urbanization that is transforming their landscape and culture. Because there is a lack of scientific evidence around the medicinal properties of local plants, the NUS Pharmacy team recognized an urgent need to document any health benefits these plants may provide before the knowledge is lost.
Evidence of anticancer benefits in 5 plants
The team focused on seven plants that people have used as traditional medicines for cancer. They were:
• Bandicoot Berry (Leea indica)
• Sabah Snake Grass (Clinacanthus nutans)
• Fool's Curry Leaf (Clausena lansium)
• Seven Star Needle (Pereskia bleo)
• Black Face General (Strobilanthes crispus)
• South African Leaf (Vernonia amygdalina)
• Simpleleaf Chastetree (Vitex trifolia)
In the study, the team prepared extracts of "fresh," "healthy," and "mature" leaves from these plants and examined their effects on cells from breast, ovarian, uterine, cervical, leukemia, liver, and colon cancers.
How plants from Mauritius could help fight cancer

Bandicoot Berry, South African Leaf, and Simpleleaf Chastetree had an anticancer effect against all seven types of cancer, according to the researchers. Fool's Curry Leaf and Black Face General also had protective properties against some cancer cells.
Interestingly, the team found that Sabah Snake Grass was not effective at preventing the growth of cancerous cells, despite many people with cancer in the region using it.
The authors hypothesize that people commonly use Sabah Snake Grass as a traditional medicine because it offers some kind of benefit to people with cancer other than killing cancerous cells.
Implications for new cancer therapies
"Medicinal plants have been used for the treatment of diverse ailments since ancient times," says lead study author Koh Hwee Ling, "but their anticancer properties have not been well studied."
"Our findings provide new scientific evidence for the use of traditional herbs for cancer treatment, and pave the way for the development of new therapeutic agents."
Koh Hwee Ling
Koh and colleagues add that further research is required to identify the active compounds that provide the anticancer effects associated with these plants. They also caution against people with cancer attempting to self-medicate using these plants without first consulting their doctor.
Recently, Medical News Today looked at some other studies that evaluated the anticancer properties of plants. One of these was a 15-year-long study into a small flowering plant called the Madagascar periwinkle.
Scientists have been aware for more than 60 years that this plant has beneficial properties for people with cancer, but until recently, they had been unable to fully understand or replicate its mechanism of action.
Earlier this month, MNT looked at a study that found that medicinal herbs grown in Mauritius contain chemical compounds that may help treat esophageal cancer.
The authors of that study argued that maintaining global biodiversity is key to ensuring the discovery and development of breakthrough therapies now and in the future.

Dopamine deficiency: What you need to know


D
opamine is a chemical found naturally in the human body. It is a neurotransmitter, meaning it sends signals from the body to the brain.
Dopamine plays a part in controlling the movements a person makes, as well as their emotional responses. The right balance of dopamine is vital for both physical and mental wellbeing.
Vital brain functions that affect mood, sleep, memory, learning, concentration, and motor control are influenced by the levels of dopamine in a person's body. A dopamine deficiency may be related to certain medical conditions, including depression and Parkinson's disease.
A dopamine deficiency can be due to a drop in the amount of dopamine made by the body or a problem with the receptors in the brain.
Symptoms
Sad and depressed woman with low dopamine levels. alone in thought.
A dopamine deficiency is associated with depression, but researchers are still investigating this complex link.
The symptoms of a dopamine deficiency depend on the underlying cause. For example, a person with Parkinson's disease will experience very different symptoms from someone with low dopamine levels due to drug use.
Some signs and symptoms of conditions related to a dopamine deficiency include:
·         muscle cramps, spasms, or tremors
·         aches and pains
·         stiffness in the muscles
·         loss of balance
·         constipation
·         difficulty eating and swallowing
·         weight loss or weight gain
·         gastroesophageal reflux disease (GERD)
·         frequent pneumonia
·         trouble sleeping or disturbed sleep
·         low energy
·         an inability to focus
·         moving or speaking more slowly than usual
·         feeling fatigued
·         feeling demotivated
·         feeling inexplicably sad or tearful
·         mood swings
·         feeling hopeless
·         having low self-esteem
·         feeling guilt-ridden
·         feeling anxious
·         suicidal thoughts or thoughts of self-harm
·         low sex drive
·         hallucinations
·         delusions
·         lack of insight or self-awareness
Causes
Dopamine model 3D render.
Dopamine deficiency may be influenced by a number of factors. Existing conditions, drug abuse, and an unhealthy diet may all be factors.
Low dopamine is linked to numerous mental health disorders but does not directly cause these conditions.
The most common conditions linked to a dopamine deficiency include:
·         depression
·         schizophrenia
·         psychosis, including hallucinations or delusions
·         Parkinson's disease
In Parkinson's disease, there is a loss of the nerve cells in a specific part of the brain and loss of dopamine in the same area.
It is also thought that drug abuse can affect dopamine levels. Studies have shown that repeated drug use could alter the thresholds required for dopamine cell activation and signalling.
Damage caused by drug abuse means these thresholds are higher and therefore it is more difficult for a person to experience the positive effects of dopamine. Drug abusers have also been shown to have significant decreases in dopamine D2 receptors and dopamine release.
Diets high in sugar and saturated fats can suppress dopamine, and a lack of protein in a person's diet could mean they do not have enough l-tyrosine, which is an amino acid that helps to build dopamine in the body.
One interest study found that people who are obese and have a certain gene are more likely to be dopamine deficient too.
Diagnosis
There is no reliable way to directly measure levels of dopamine in a person's brain.
There are some indirect ways to determine a dopamine level imbalance in the brain. Doctors can measure the density of dopamine transporters that correlate positively with nerve cells that use dopamine. This test involves injecting a radioactive material that binds to dopamine transporters, which doctors can measure using a camera.
A doctor will look at a person's symptoms, lifestyle factors, and medical history to determine if they have a condition related to low levels of dopamine.
Treatment
Omega-3 fatty acid supplements.
Omega-3 fatty acid supplements may help to boost dopamine levels naturally.
Treatment of dopamine deficiency depends on whether an underlying cause can be found.
If a person is diagnosed with a mental health condition, such as depression or schizophrenia, a doctor may prescribe medications to help with the symptoms. These drugs may include anti-depressants and mood stabilizers.
Ropinirole and pramipexole can boost dopamine levels and are often prescribed to treat Parkinson's disease. Levodopa is usually prescribed when Parkinson's is first diagnosed.
Other treatments for a dopamine deficiency may include:
·         counseling
·         changes in diet and lifestyle
·         physical therapy for muscle stiffness and movement problems
Supplements to boost levels of vitamin Dmagnesium, and omega-3 essential fatty acids may also help to raise dopamine levels, but there needs to be more research into whether this is effective.
Activities that make a person feel happy and relaxed are also thought to increase dopamine levels. These may include exercise, therapeutic massage, and meditation.
What is early-onset Parkinson's disease?

Dopamine vs. serotonin
Dopamine and serotonin are both naturally occurring chemicals in the body that have roles in a person's mood and wellbeing.
Serotonin influences a person's mood and emotions, as well as sleep patterns, appetite, body temperature, and hormonal activity, such as the menstrual cycle.
Some researchers believe that low levels of serotonin contribute to depression. The relationship between serotonin and depression and other mood disorders is complex and unlikely to be caused by a serotonin imbalance alone.
Additionally, dopamine affects how a person's moves, but there is no clear link to the role of serotonin in movement.
Outlook
Dopamine deficiency can have a significant impact on a person's quality of life, affecting them both physically and mentally. Many mental health disorders are linked to low levels of dopamine. Other medical conditions, including Parkinson's disease, have also been linked to low dopamine.
There is limited evidence that diet and lifestyle can affect the levels of dopamine a person creates and transmits in their body. Certain medications and some therapies may help relieve symptoms, but a person should always speak to a doctor first if they are concerned about their dopamine levels.
