Chemotherapy Can Lead To Nerve Damage Called The Peripheral Neuropathy, Know What It Means

Updated Jan 30, 2025 | 11:00 PM IST

SummaryUnder this condition, which can result from traumatic injuries, infections, metabolic problems, or could be inherited due to exposure to toxins, people may experience stabbing, burning, or tingling pain.
Is Chemotherapy Safe?

Many of those who are diagnosed with cancer undergo chemotherapy, an experience that though, is life-saving, but causes severe pain. A new study published in the Regional Anesthesia & Pain Medicine found that patients undergoing chemo therapy experience severe nerve pain and that 40% of chemotherapy-treated patients develop painful peripheral neuropathy.

What happens in Peripheral Neuropathy?

The peripheral nervous system sends information to the brain and the spinal cord, also known as the central nervous system, to the rest of the body through motor nerves. The peripheral nerves also send sensory information to the central nervous system through sensory nerves.

Under this condition, which can result from traumatic injuries, infections, metabolic problems, or could be inherited due to exposure to toxins, people may experience stabbing, burning, or tingling pain.

The symptoms too can vary on the person and the severity of the case:

  • Sensory nerves that receive sensation can be damaged, for instance the nerves that tells you about temperature, pain, vibration or touch.
  • Motor nerves that control muscle movement could be damaged.
  • Autoionic nerves that control functions like blood pressure, sweating, heart rate, digestion, or bladder function could be damaged too.

What Is Chemotherapy-induced Peripheral Neuropathy?

Peripheral neuropathy occurs when chemotherapy drugs damage nerves outside the brain and spinal cord. This can disrupt normal nerve signaling, causing symptoms like:

  • Tingling or numbness
  • Burning or "pins and needles" sensations
  • Weakness
  • Loss of balance and coordination
This condition is not just temporary discomfort—it can persist for months or even years after treatment, significantly impacting a patient's quality of life.

Who Are At Risk?

  • The researchers after reviewing data from 77 studies which involved 11,000 patients across 28 countries found that those who are prescribed platinum-based and taxane chemotherapy drugs carry the highest risk of nerve pain.
    Lung cancer patients too are most affected. The study showed that more than 62% who developed neuropathy, were likely due to frequent and prolonged chemo cycles.

  • Furthermore, the study also found that people with ovarian cancer, around 32% and lymphoma around 36% had the lowest reported risk.
  • But, why does this happen?

    The reason is that while chemotherapy is actually designed to target cancer cells, it damages healthy cells too. These include healthy cells in nervous system. Chemotherapy kills cells that are in the process of dividing into 2 new cells. It also damages the genes inside the nucleus, which is the reason why it targets all and any cells which are in process of dividing into two. The exact mechanism behind nerve pain is however unclear, though the researchers believe that chemotherapy may alter nerve signaling in ways that could lead to chronic pain.

    The Way Forward

    The study highlights an urgent need for research into how chemotherapy causes nerve damage and how to prevent or manage it. Scientists are now focusing on potential therapies to protect nerves while ensuring cancer treatments remain effective.

    For cancer patients undergoing chemotherapy, discussing potential nerve pain risks with their doctor—and exploring possible preventative measures—may help improve long-term outcomes.

    Harvard Psychologist Lists Careers Linked To Higher Rates Of Suicide: Doctors Maybe At High Risk Themselves

    Updated Sep 17, 2025 | 06:52 PM IST

    SummaryWe lose more and more people to suicide every year. Being named one of the leading reasons for death, it is a topic that most people shy away from. However, this Harvard doctor says otherwise. In a podcast interview, Dr. Matthew Nock speaks on suicide and people who are at risk for it.

    Suicides are one of the leading causes of death around the world. While it is easy to say that the person who chose to take their lives did it of their own violation, Harvard psychologist Dr. Matthew Nock, explains the other side. “90% of people who try and kill themselves say, I didn't want to die per se. I wanted to escape from seemingly intolerable.” Speaking on the On Purpose podcast with Jay Shetty, Dr. Nock pointed out that the link between work pressure and suicidal thoughts varies by race and ethnicity.

    The concerning rise in suicide cases tied to work pressure has fueled a social media conversation about toxic work culture. What was once considered a normal part of the professional grind is now being openly challenged, as people share personal stories of the anxiety, depression, and isolation caused by unhealthy work environments.

    What Professions Are At High Risk Of Suicide?

    According to Dr. Matthew Nock, certain careers are linked to a higher risk of suicide.

    Police Officers

    He noted that physicians and police officers are among those at high risk. He mentioned a spike in suicides among New York City police officers, who are predominantly white men, and shared that female police officers, in particular, face a higher risk, even when accounting for factors like age, race, and ethnicity.

    According to a 2025 study published in the Police Practice and Research, on average, 21.4 out of every 100,000 officers died by suicide each year.

    The study showed that the suicide rate was much higher for male officers (22.7 per 100,000) than for female officers (12.7 per 100,000).

    Physicians

    Dr. Nock explained that access to means is a significant factor in these high-risk professions, which helps explain why physicians, police officers, and military members have a much higher risk of suicide compared to others.

    Another study published in 2024 The BMJ, showed that the number of suicides among doctors has been going down, female doctors are still at a much higher risk than other people.

    When looking at all the data, male doctors were found to have a 5% higher risk of suicide compared to the general population.

    In a more recent analysis of the last few years, the overall suicide rate for doctors has decreased, which is good news. But even with this improvement, female doctors still have a 24% higher risk than the general public.

    Why We Need To Talk More About Suicide

    Dr. Nock stresses the importance of openly discussing suicide, particularly in schools. He compared it to fire drills or earthquake preparedness, saying that since 15% of people will experience suicidal thoughts, it's crucial to equip everyone with a safety plan..Dr. Matthew Nock said, "We know that asking about suicide, talking about suicide, does not make people suicidal."

    He noted that the people who act on suicidal thoughts often show different signs than those who just have the thoughts. While depression is a strong predictor of having suicidal thoughts, other factors like anxiety, aggressiveness, poor behavioral control, and drug or alcohol use are more closely linked to a person actually attempting suicide.

    He believes that a small educational module on suicide in health class could help save lives by teaching people what to do if they or someone they know is struggling.

    Lung Cancer Rates Linked With Pollution Are Down In US, But THIS Country Is Still Suffering: Study

    Updated Sep 17, 2025 | 11:00 PM IST

    SummaryRecent studies have shown that pollution is one of the reasons behind the rising cases of cancer throughout the world. Although the harmful pollutants that were responsible for these cancer cases have gone down for some countries like US, the same cannot be said for others, according to a new study.

    While we all know air pollution affects our health, did you know that it was actually driving cancer cases higher? This has led to a big rise in health problems worldwide. Past studies show that air pollution is linked to about seven million premature deaths each year and contributes to over 3% of all years of healthy life lost globally. This revelation was a big concern for public health, and to fix it, many measures were taken.

    While some countries like the US showed promising results in bettering public health, a recent study in the International Journal of Public Health showed that this positive trend is not yet showed up in China.

    How Is PM2 Pollution Affecting Our Health?

    One of the most dangerous types of air pollution is called fine particulate matter, or PM2.5. These tiny particles come from car exhaust, factory smoke, and even from the smoke created by burning solid fuels inside homes. Because they are so incredibly small, they can stay suspended in the air for a long time and, when we breathe them in, they go deep into our lungs.

    Once inside the body, PM2.5 can cause inflammation and even change our genes, which increases our risk for many illnesses, especially tracheal, bronchial, and lung (TBL) cancers. A new study looked at how much PM2.5 pollution has affected TBL cancer rates in China, Japan, South Korea, and the United States from 1990 to 2021.

    Has Pollution-Related Health Risk Decreased Everywhere?

    The study, which used data from the Global Burden of Disease (GBD) project, found some important trends:

    Overall Cancer Rates Are Declining

    The good news is that globally, the number of deaths and years of healthy life lost due to TBL cancer linked to PM2.5 pollution are going down. This positive trend was consistent in all the countries studied: China, Japan, South Korea, and the U.S.

    China's Unique Challenge

    Despite this global trend, China faced a much higher death rate from TBL cancer linked to PM2.5 compared to the other three countries. While their rates are decreasing, they still remain significantly higher than the worldwide average.

    Household Pollution Hits Women Harder

    The research also looked at pollution from burning solid fuels inside homes. The global death rate from TBL cancer linked to this type of pollution has remained stable, but it's actually increasing for women while it's decreasing for men. This highlights a specific danger for women in homes that rely on these fuels.

    Will This Pollution Cancer Trend Keep Rising?

    Looking ahead, researchers predict that the global death rate for TBL cancer caused by PM2.5 will actually increase over the next 29 years. However, the study notes that countries like China, South Korea, and the U.S. are expected to see a significant drop in their rates, while Japan's numbers are expected to stay about the same.

    Overall, this study shows that while air pollution is a serious global health risk, the efforts to reduce PM2.5 exposure in many countries are making a real, positive difference.

    Maintaining our gut health is not as easy as it seems. Even things like how you do your bowel movements could reveal how healthy your gut actually is. According to Dr. Saurabh Sethi, a board-certified gastroenterologist, many of us are making common mistakes on the toilet that can lead to real health problems. Here are three crucial habits to change to improve your gut health. Here are three mistakes' people make will they are in the washroom.

    3 Bathroom Mistakes You Are Making

    Stop Straining

    Pushing or straining when you poop can cause serious issues like hemorrhoids, which are swollen veins in your rectum and anus, and anal fissures, which are small tears in the lining of your anus. In more severe cases, it can even lead to rectal prolapse, where part of the rectum slides out of the anus. Instead of forcing it, focus on taking deep breaths. This helps your abdominal muscles relax and allows your body to do its job naturally, reducing the risk of painful complications.

    Put Down Your Phone

    Scrolling on your phone while on the toilet can be a bad habit. Spending extra time on the toilet, even if you’re not straining, puts pressure on the delicate veins in your rectum. This can cause them to swell, significantly increasing your risk of hemorrhoids. To protect yourself, it’s best to keep your bathroom breaks short—ideally, under five minutes.

    Don't Ignore the Urge

    When you feel the need to poop, it's important not to hold it in, which makes it much more difficult to pass later, leading to and worsening constipation. When you feel the need to go, listen to your body. Holding it in causes your stool to get harder and drier, which makes constipation much worse and more painful later on. Train your gut to go when it says it's time.

    Simple Ways To Improve Your Bowel Movements

    Go at the Same Time Each Day

    Try to create a routine. If you're often straining without success, try sitting on the toilet about 30-60 minutes after a meal, when your colon is naturally more active. A little stretching or a short walk beforehand can also help things get moving.

    Use a Stool for Your Feet

    The natural position for a bowel movement is squatting. You can mimic this position on a regular toilet by placing a small stool under your feet to raise your knees above your hips. This simple change helps your muscles relax and can make bowel movements easier and more complete.

    Focus on Fiber and Fluids

    Fiber is essential for creating soft stool that's easy to pass. Most adults should aim for 25 to 35 grams a day. Just remember to add it to your diet slowly. As you increase your fiber, be sure to drink more water and other non-caffeinated fluids, since caffeine can dehydrate you and make stool harder.

    When to Seek Help

    While these tips are a great starting point, sometimes you need more personalized help. You should talk to your doctor if you notice any of these signs:

    • A recent, unexplained change in your bowel habits
    • Blood in your stool
    • Unexplained stomach pain
    • A pelvic health physical therapist can also provide a full evaluation and create a personalized plan to improve your bowel health.
