How does age affect cancer

Age plays an important role in the development of cancer, as the passing of years increases the chances that the body's cells will undergo mutations and damage, which can lead to cancer. However, cancer can occur at any age, and other factors such as genetics, lifestyle and environmental factors are also important in the development of the disease.

1. Accumulation of damage at the cellular level:
   Over the years, the body's cells accumulate damage to their DNA due to various factors such as free radicals, environmental pollution, poor diet, and genetic factors. This damage to DNA can cause mutations that can lead to the development of cancer. The more time that passes, the more likely it is that this damage will accumulate and develop the disease.
2. Distribution of harmful cells:
   As we age, the body becomes less efficient at repairing cellular damage and eliminating harmful cells. The body's immune system also weakens with age, making it harder to fight and prevent the development of cancer cells.
3. Different types of cancer and age:
   Some types of cancer are more common in older people, while others can occur at younger ages. For example:
   ⦁ Breast cancer and prostate cancer are more common in older individuals (after age 50).
   ⦁ Leukemia and some types of lymphoma can affect children and young adults.
   ⦁ Lung cancer and colorectal cancer are also more common in older adults.
4. Genetic mutations and inheritance:
   While some cancer-causing mutations may occur by chance, some individuals may have a genetic predisposition to developing cancer. These genetic mutations, such as those associated with the BRCA1 and BRCA2 genes (which increase the risk of breast and ovarian cancer), can increase the risk of developing cancer even at a younger age.
5. Hormonal differences and age:
   Hormonal changes that occur throughout life can also influence the development of some types of cancer, such as breast and prostate cancer. For example, estrogen and progesterone levels in women can influence the development of breast cancer.
