Where is breast cancer acquired?

Although breast cancer is much more common in women, this form of cancer can also develop in men. In both women and men, the most common form of breast cancer begins in cells lining the milk ducts (ductal cancer). In women, cancer can also develop in the glands that produce milk (lobular cancer ).

Where do most breast cancers occur?

Several studies have found that the upper outer quadrant of the breast is the most frequent site for breast cancer occurrence.

How is breast cancer acquired?

Up to 10% of all breast cancers are hereditary forms, caused by inherited germ-line mutations in “high-penetrance,” “moderate-penetrance,” and “low-penetrance” breast cancer susceptibility genes. The remaining 90% of breast cancers are due to acquired somatic genetic and epigenetic alterations.

Where is the breast cancer gene located?

In 1990, DNA linkage studies on large families with the above characteristics identified the first gene associated with breast cancer. Scientists named this gene “breast cancer 1” or BRCA1 (pronounced brak-uh). BRCA1 is located on chromosome 17.

What part of the body does breast cancer generally affect?

In theory, breast cancer can spread to any part of the body, but it most commonly spreads to the lymph nodes, lungs, liver, bones and sometimes the brain.

Does stress cause breast cancer?

Many women feel that stress and anxiety caused them to be diagnosed with breast cancer. Because there has been no clear proof of a link between stress and a higher risk of breast cancer, researchers in the United Kingdom conducted a large prospective study on the issue.

Does breast cancer skip a generation?

Inherited breast cancer genes cannot skip a generation. If a person has inherited a gene that causes breast cancer, they have a 50% chance of passing it on to their children. If a person’s child does not inherit the mutated gene, the child cannot then pass it on to their future children.

Is breast cancer more common in left breast?

Breast cancer is more common in the left breast than the right. The left breast is 5 – 10% more likely to develop cancer than the right breast. The left side of the body is also roughly 5% more prone to melanoma (a type of skin cancer). Nobody is exactly sure why this is.

Is breast cancer hereditary from father side?

About 5% to 10% of breast cancer cases are thought to be hereditary, meaning that they result directly from gene changes (mutations) passed on from a parent. BRCA1 and BRCA2: The most common cause of hereditary breast cancer is an inherited mutation in the BRCA1 or BRCA2 gene.

Does everyone have BRCA genes?

Everyone has two copies of the BRCA1 and BRCA2 genes, one copy inherited from their mother and one from their father.

What happens if you are BRCA positive?

A positive test result means that you have a mutation in one of the breast cancer genes, BRCA1 or BRCA2, and therefore a much higher risk of developing breast cancer or ovarian cancer compared with someone who doesn’t have the mutation. But a positive result doesn’t mean you’re certain to develop cancer.

Does your body ache with breast cancer?

It’s also possible for breast cancer to spread to the muscles and bones. You may have pain in these areas as well as restricted movement. Your joints can feel stiff, especially right after you wake up or stand up from sitting for long periods of time.
