: Young peoples’ lifestyles affect their chances of getting cancer later in life.

Answer 1

Young peoples’ lifestyles affect their chances of getting cancer later in life...wrong by the following postulatesRisk Factors and Causes of Cancers in Young Adults

Cancer occurs as a result of changes (mutations) in the genes inside our cells. Genes, which are made of DNA, control nearly everything our cells do. Some genes control when our cells grow, divide into new cells, and die. Changes in these genes can cause cells to grow out of control, which can sometimes lead to cancer.

A risk factor is anything that increases your chances of getting a disease such as cancer. Different cancers have different risk factors. In many cases, it’s not clear what causes the gene changes that lead to cancer.

Inherited gene changes

Some people inherit gene mutations from a parent that increase their risk of certain cancers. In people who inherit such a mutation, this can sometimes lead to cancer earlier in life than would normally be expected. Examples include:

• BRCA gene mutations, which increase the risk of breast, ovarian, and some other cancers
• Lynch syndrome (caused by DNA mismatch repair gene mutations), which increases the risk of colorectal, ovarian, endometrial, and some other cancers
• Familial adenomatous polyposis (caused by APC gene mutations), which increases the risk of colorectal cancer
• Li-Fraumeni syndrome (most often caused by TP53 mutations), which increases the risk of certain leukemias, sarcomas, and some other cancers 
•  

Still, most cancers in young adults are not caused by inherited gene changes.
