Cancer Prevention Focuses on Immune Strength and Healthy Aging
Dr. Kalluri, a cancer expert, talked about how our bodies fight cancer.
He said cells get damaged all the time, but our bodies usually fix them.
Sometimes, these damages turn into cancer, but it takes a long time—about 15 to 20 years.
He explained that our immune system helps stop these damaged cells from causing problems.
He also said that as we get older, we get more of these damages, but our bodies still keep most of them under control.
To prevent cancer, he suggested making our immune system stronger and helping our bodies age healthier.
He mentioned that some people might have cancer cells but never get sick.
He also talked about new ways to fight cancer, like targeting a gene called KRAS that causes pancreatic cancer.
Cells face constant damage, and the body works to repair it, but mutations can accumulate over time.
The p53 gene, known as the guardian of the genome, is the most frequently mutated gene in cancer.
It typically takes 15–20 years for a normal cell to transform into cancer, with silent lesions persisting for long periods.
Strong immunity is central to cancer prevention, with efficient DNA repair, controlled inflammation, and balanced metabolism delaying or preventing malignancy.
Up to 35% of individuals over 40 may harbor cancer cells without ever developing symptoms.
