Chemotherapy can accelerate biological aging, with studies suggesting it might add the equivalent of 10 to 20 years of physiological aging, depending on the drugs used, with anthracycline-based regimens potentially causing larger effects (around 23-27 years) compared to others. This "biological aging" is measured by changes in DNA methylation and cellular markers like p16INK4a, indicating increased risk for age-related conditions, though the long-term clinical impact and reversal potential (e.g., with exercise) are still being studied.
Dr. Shahrukh Hashmi's research explains that the reason for accelerated aging in cancer patients is that chemotherapy and radiation therapy, in addition to killing cancer cells, also kill normal, healthy tissue cells.
Most chemotherapy side effects go away in time, but some can linger and require monitoring or treatment. Possible long-term side effects of chemo include damage to your heart and peripheral neuropathy, in which damaged nerves can cause pain, weakness or numbness in the extremities – arms, hands, legs and feet.
Hydration is the key to maintaining your skin. While drinking a lot of water is helpful for hydrating on the inside, it's also really important to hydrate our bodies on the outside. Dryness can cause discomfort, tearing of the tissue and aging skin.
Of course, chemo drugs do target fast replicating cells and because skin, hair, nails, lips and the digestive tract are fast replicating, the drugs attack them too.
In some cases, chemotherapy can cause long-term problems for the heart, lungs, nerves, kidneys and reproductive or other organs. Further, certain types of chemotherapy may have delayed effects, such as a second cancer, that develop many years later.
Radiation therapy and chemo are often combined to treat cancer. While both treatments are effective, chemo generally produces more serious side effects than radiation therapy. How radiation therapy is used to treat cancer. American Cancer Society.
How long does chemo stay in your body? Chemotherapy stays in your body for two to three days (48 to 72 hours). Some drugs can take up a week for your body to break them down. Once the kidneys and liver break down the chemo, your body excretes the remnants through urine, sweat, stool and vaginal fluid (in women).
“Hydration is important, even before you start chemo.” “Always remember, chemo is our weapon, not our enemy.” “Find your breasties—they're a wonderful bunch. Drink lots of water, rest when needed, and try to get out for walks when you can.
The chemotherapy drug fluorouracil (5FU) comes in a cream called Efudix. You spread the cream on your skin. This is called topical chemotherapy. It treats the cancer cells where you apply it. Very little of the drug is absorbed into the rest of your body.
Alcohol: Drinking too much alcohol can dehydrate and damage your skin over time, leading to signs of premature aging. Poor sleep: Studies show that low quality (or not enough) sleep makes your cells age faster. Stress: When you're stressed, your brain pumps out cortisol, a stress hormone.
Some eye and vision problems may be permanent or occur as late effects. Treatment that uses drugs to kill or destroy specific cells (such as cancer cells), viruses, bacteria or other micro-organisms. drugs, such as cytarabine, cisplatin, methotrexate and vincristine, can cause photophobia, cataracts and vision changes.
Additionally, treatments such as chemotherapy and endocrine therapy were linked to increased biological aging. One year after diagnosis, chemotherapy was associated with the most significant rise in PAA, while endocrine therapy had long-term effects, increasing aging markers even ten years after treatment.
Doesn't the benefit of chemotherapy decrease with age? In most cases, it does not. A healthy older person often has the same chances of responding to treatment or being cured than a younger one.
If you were treated with certain types of chemotherapy, you can also have many of the same problems. Some problems go away after treatment. Others last a long time, while some may never go away. Some problems may develop months or years after your treatment has ended.
The Median Duration of Response tells you how long your cancer can be expected to respond to the chemotherapy, before the cancer starts growing again. For most cancers where palliative chemotherapy is used, this number ranges from 3-12 months. The longer the response, the longer you can expect to live.
After a chemotherapy infusion, the body must recover from the harsh chemicals. Ways to flush chemo out of body include staying hydrated, eating nutrient-rich foods, and supporting liver and kidney function.
Types of cancer that are treated with radiation therapy
Brachytherapy is most often used to treat cancers of the head and neck, breast, cervix, prostate, and eye. A type of brachytherapy called radioembolization may be used to treat liver cancer or cancer that has spread to the liver.
Fatigue from chemotherapy tends to be the worst a few days after treatment and then gets better before the next treatment. Fatigue from radiation can start slowly after a few weeks of treatment and get worse as treatment goes on. It may last many months after treatment is finished.
While chemotherapy aims to keep the disease from spreading, radiation focuses on particular cells. Chemotherapy can also affect the entire body, while radiation repairs only the affected cells. Both treatments can cause side effects, including hair loss, nausea and fatigue.
Chemotherapy can reduce the production of blood cells made in the bone marrow. This can lead to low blood cell counts, which are the most common side effect of chemotherapy. There are different types of low blood cell counts.
You might have physical changes like hair loss, skin changes or new scars, ostomies, weight changes, or loss of limbs. Cancer and treatment might also cause changes to your sex organs, sexual health, fertility, or mental health. Some of the changes may be temporary, while others are permanent.
Signs of improvement can show up early in chemotherapy. These signs include tumor shrinkage on scans, lowered tumor marker levels in blood tests, and better blood counts. Healthline says these signs help doctors see if treatment is working.
