Can boosting immunity prevent cancer development at 35?

Question

Hello, Doctor,

I came across some information saying our immune system destroys abnormal cells every day before they become cancer, which sounded surprising. I wanted to understand if this is scientifically true. Please tell me,

What percentage of cancer cells does a healthy 35-year-old's immune system destroy daily?
Does this mean cancer develops only when the immune system fails to detect these cells?
Can lifestyle or immunity improvement actually help prevent cancer development?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

I would like to tell you that your question is very good, and it comes to the mind of many people. Our immune system is very strong, and it is designed to recognize abnormal cells and deal with them. However, cancer is not that simple.

Cancer cells develop changes in their DNA (deoxyribonucleic acid) and start multiplying in huge numbers, more than the body and immune system can control. In addition, cancer cells can change their appearance to become very similar to normal body cells, because they originate from the body itself. So, the immune system cannot easily recognize them.

That is why immunotherapy drugs are now designed to help the immune system identify and attack cancer cells, and they are making significant progress. Environmental factors also affect the ability of the immune system to fight cancer.

In general, our immunity can fight abnormal cells in many situations, but sometimes the immune system fails, and sometimes cancer cells become stronger than the immune system, which leads to disease.

It is very important to take care of the immune system, focus on good nutrition, eat healthy food, and follow a healthy lifestyle. This helps us resist disease before it appears and helps control it if it occurs.

I hope this information helps you.

Feel free to ask further queries.

Thank you.
