A Deep Dive into Anti-Cancer Drugs: How Do They Work, and What Does the Body Need During Treatment?
A deep dive into anti-cancer drugs: how do they work, and what does the body need during treatment? In today's world of modern medicine, anti-cancer drugs are one of the most important weapons in the fight against cancer, a disease that claims the lives of millions of people in Thailand and around the world every year. But the key question is: how do these drugs actually work? And what does a patient's body need while undergoing treatment with them? Let's take a detailed look at this topic, together with guidance on caring for the body properly through nutrition — especially supplementing protein through protein shakes, an important tool for restoring healthy cells, reducing side effects, and improving treatment effectiveness.
What are anti-cancer drugs? Anti-cancer drugs are a group of medications specifically designed to inhibit the growth of, or destroy, cancer cells. There are many types of these drugs, which can be divided according to their mechanism of action as follows.
- Chemotherapy These drugs work by destroying rapidly dividing cells, which includes cancer cells, but they may also affect healthy cells such as those in the bone marrow, intestines, or skin, leading to side effects such as hair loss, nausea, and lowered immunity.
- Targeted therapy Drugs in this group work by targeting specific molecules or genes within cancer cells — for example, inhibiting an enzyme that cancer cells need to grow — thereby reducing the impact on normal cells.
- Immunotherapy These drugs stimulate the body's own immune system to detect and eliminate cancer cells effectively, without relying directly on chemical agents.
- Hormonal therapy Used for certain hormone-related cancers, such as breast cancer and prostate cancer, by lowering the levels of hormones that fuel cancer growth.
How does the body respond to anti-cancer drugs? Although anti-cancer drugs are aimed at destroying cancer cells, they can also affect normal cells, especially those that divide rapidly, such as:
- Red and white blood cells — leading to anemia and reduced immunity
- Cells lining the intestines — causing mouth sores, diarrhea, and nausea
- Muscle and energy levels — resulting in fatigue, muscle wasting, and chronic weakness
- The digestive system — loss of appetite, weight loss, and deficiency of essential nutrients
Nutrition for patients undergoing treatment with anti-cancer drugs For treatment to be effective, patients should receive close nutritional care, particularly to restore and protect healthy cells that may be damaged by the medication.
Protein: an essential helper for repairing cells and boosting immunity The bodies of cancer patients need more protein than the average person because it:
- Helps repair cells damaged by medication The body has the ability to heal itself, and with proper nourishment it can effectively repair cells damaged by the side effects of certain drugs.
- Rebuilds lost muscle mass Getting adequate protein along with appropriate exercise helps rebuild lost muscle mass and restore strength, especially in patients or elderly individuals.
- Stimulates the production of new blood cells Certain nutrients, especially iron and vitamin B12, play an important role in stimulating the production of new blood cells, which are essential for transporting oxygen and supporting the body's recovery.
- Strengthens immunity to better fight germs and cancer cells A strong immune system helps the body fight off germs and cancer cells more effectively. Nourishing the body with the right nutrients is therefore an important way to reinforce this protective shield.
Protein shakes: an easy-to-digest and safe option During periods when patients are unable to eat a normal diet — due to loss of appetite, vomiting, or difficulty swallowing — protein shakes become an important aid because they:
- Are easy to digest and absorb quickly, without adding extra burden Choose a supplement that the body can digest and absorb quickly without placing a burden on the digestive system, which is especially important for patients or those with a weakened digestive system.
- Provide an immediate protein boost Protein can be supplemented right away, even during meals when patients or elderly individuals can only eat a small amount, ensuring the body still receives the nutrients it needs for repair and muscle building.
- Add energy appropriately They help boost the body's energy appropriately, without excessively spiking blood sugar levels, which is especially beneficial for those who need to manage their blood sugar.
- Contain vitamins, minerals, and antioxidants Some supplement formulas also contain a full range of vitamins, minerals, and antioxidants, which support the body's overall recovery process and protect cells from damage.
Other nutrients to supplement during treatment
- Iron and folate to support blood cell production
- Vitamins C and E antioxidants that reduce cellular inflammation
- Omega-3 reduces inflammation at the cellular level and helps the immune system function better
Sample meal plan for cancer patients undergoing treatment with anti-cancer drugs
- Breakfast Clear fish congee + boiled vegetables, 1 glass of protein shake (low-fat, sugar-free formula)
- Lunch Brown rice + finely minced boiled chicken + boiled carrots, clear vegetable soup
- Snack Mashed ripe banana + low-fat yogurt, 1 glass of protein shake (formula enriched with vitamin C and iron)
- Dinner Shiitake mushroom congee + steamed white tofu + steamed pumpkin, hot herbal tea (such as pandan leaf or ginger)
When medication and nutrition work together effectively, treating cancer with anti-cancer drugs requires more than medication alone. Proper nutrition — especially supplementing with an easy-to-digest protein source like protein shakes — helps the body recover faster, reduces side effects, and increases the chances of successful treatment.
