Cancer is genetic but is not inherited. This means that all cancer happens due to damage
to DNA, but it will not be passed down to future generations. Do you agree with this
statement? Explain your position.
The statement that cancer is genetic but not inherited is partially correct. Cancer is indeed
caused by damage to DNA, which can occur spontaneously or as a result of exposure to
environmental factors such as tobacco smoke, radiation, or certain chemicals. However, some
types of cancer can also be caused by inherited genetic mutations that increase a person's risk
of developing the disease.
For example, mutations in the BRCA1 and BRCA2 genes are associated with a higher risk
of breast and ovarian cancer, while mutations in the APC gene are associated with a higher risk
of colon cancer. These genetic mutations can be inherited from a person's parents, and they can
increase the risk of cancer in the individuals who carry them as well as in their children.
According to the American Cancer Society, "about 5% to 10% of all cancers are caused
by inherited gene mutations." So, it is clear that not all cancer is caused by inherited genetic
mutations, but some types of cancer are.
In addition, it is important to note that even in the absence of inherited genetic mutations,
a person's family history can still influence their risk of cancer. Family members of a person with
cancer may be more likely to develop the disease themselves due to shared environmental
exposures or lifestyle factors.
In conclusion, while it is true that cancer is caused by damage to DNA, some types of
cancer can also be caused by inherited genetic mutations. It is important to consider both genetic
and environmental factors when assessing a person's risk of cancer, and to understand that family
history can play a role in cancer risk even in the absence of inherited genetic mutations.
