Is anyone aware of a correlation between melanoma and breast cancer?


CAdesiree - (7/11/2011 - 2:31pm)

i am new to melanoma.  but i think i read something about it increasing your chances of breast cancer by 50%.  scared the **** out of me.  both my grandmothers died with breast cancer, and my mother had diseased ducts removed.  but i read that one night i couldnt sleep... so my info may be confused.

You may wish to research the BRCA2 (and perhaps BRCA1) genetic mutation. The name of this gene is called: breast cancer 2, early onset.

This may help you some too, it is from NCI:

Please keep in mind, the risk is still low, and it does not mean anyone will ever get these other cancers, just that one is at a slightly increased risk if positive for the mutation.

In addition to female breast cancer, mutations in the BRCA2 gene can also lead to an increased risk of ovarian cancer, prostate cancer, pancreatic cancer, fallopian tube cancer, male breast cancer, and of course melanoma.

Here is a post of mine from some time ago as well:

BRCA1 (breast cancer 1, early onset) is a gene in humans, in which some mutations are associated with a increase in the risk of breast cancer, as well as other cancers too.

BRCA1 belongs to a class of genes known as tumor suppressors, which maintains genomic integrity to prevent dangerous genetic changes. The multifactorial BRCA1 protein product is involved in DNA damage repair especially error-free repair of DNA double strand breaks,ubiquitination, transcriptional regulation as well as other functions.

BRCA2 (Breast Cancer Type 2 susceptibility protein) is a protein that in humans is encoded by the BRCA2 gene. BRCA2 belongs to the tumor suppressor gene family, and the protein encoded by this gene is involved in the repair of chromosomal damage with an important role in the error-free repair of DNA double strand breaks.

The BRCA1 gene accounts for about 45 percent of hereditary breast cancer, but researchers believe it is not associated with an increased risk for melanoma. The BRCA2 gene, on the other hand, has been associated not only with an increased risk for breast cancer, but also with increased risk for melanoma as well.

BRCA genetic mutations can also be found in other cancers as well such as:

Fallopian tube cancer: where lifetime risk to be less than 1% in BRCA1 and BRCA2 mutations.

Pancreatic cancer: Although studies on carriers of both BRCA1 and BRCA2 mutations have indicated an elevated lifetime risk for pancreatic cancer, they say that the the risk is small.

Primary peritoneal cancer: which is the layer of cells lining the inside of the abdomen. The risk for primary peritoneal cancer is still very low in both mutation carriers: one study estimated the lifetime risk in BRCA carriers to be 1.3%, while another study found the risk to be 3.5%.

Prostate cancer: where Both BRCA1 and BRCA2 have been linked with an increased risk factor for prostate cancer.

Stomach cancer: where carriers of a BRCA2 mutation may have a slightly increased lifetime risk.

Uterine cancer: where risk is slightly increased in women who carry one of the genes.

if you are going to get cancer, breast cancer is easier to treat than should be afraid of melanoma much more than BC...i remember my breast onc saying...i wish it was BC...

i am told that BRCA2 gene defect is implicated in the melanoma i got...i am sister is also BRCA2 and she DID have BC...

i really believe cancer starts because of mutated genes you get at birth...they are finding new mutations all the time implicated in cancers...
