For many types of cancer, a portion of
those cancers are linked to a family history. Breast, ovarian, prostate,
and colon are some of these cancers. Some of these are discussed
briefly here, but only to help explain heredity and cancer. Please refer
to the American Cancer Society specific cancer site documents for more
information about a particular type of cancer and its genetic
components, diagnosis, and treatment.

Heredity and Cancer
Cancer is such a common disease that it
is no surprise that many families have at least a few members who have
had cancer. Sometimes, certain types of cancer seem to run in some
families. This can be caused by a number of factors. It can be because
family members have certain risk factors in common, such as smoking,
which can cause many types of cancer. It can also be due in part to some other factors, like obesity, that tend to run in families and influence cancer risk.
But in some cases the cancer is caused
by an abnormal gene that is being passed along from generation to
generation. Although this is often referred to as inherited cancer,
what is inherited is the abnormal gene that can lead to cancer, not the
cancer itself. Only about 5% to 10% of all cancers are inherited –
resulting directly from gene defects (called mutations) inherited from a parent. This document focuses on those cancers.

how to remove black spots on face
Many black spots or dark patches can be easily lightened or eliminated to restore a glowing facial complexion. Dark spots, patches and other marks on the face may be due to excess secretion of melanin on the skin. Some factors that can lead to this condition include over exposure to the sun, hormone imbalance, pregnancy, certain medications, vitamin deficiencies, lack of sleep and too much stress.
Spots and patches on the face can be embarrassing and even lead to low self-esteem. Luckily, there are many possible treatments, such as acid peels and laser surgeries. Simple, natural homemade remedies also may reduce the appearance of spots and other blemishes on your face.
