Metastatic Breast Cancer: Skin Cancer (aka Melanoma)

From the first moment my wife discovered she had breast cancer, there was a deafening silence from the men I know. Even ones whose wives, mothers or girlfriends had breast cancer seemed to have received a gag order from some Central Cancer Command and did little more than mumble about the experience. Not one to shut up for any known reason, I started this blog…

“Where’d this come from?”

Well, see, my brother, sister, and sister-in-law were all diagnosed with skin cancer and successfully treated. As well, an old friend and teaching colleague of mine was recently diagnosed and treated for skin cancer. (The worst part there was that he’d posted a picture of the excision on FaceBook and many (if not all) of US teased him about bonking his head, etc. Thoroughly stung when he later announced that it was a cancerous spot removed, I apologized both on his timeline and to him in person. NOT that I “should have known”, even so...)

Lately, I’ve had these dry, red patches on my face and while using lotion makes them fade, I have (duh) been wondering if they were signs of skin cancer. That led – at least in my mind – to wondering if there was any connection between breast cancer and skin cancer.

Not surprisingly, there is: “Since breast cancer is the most frequently diagnosed non-cutaneous (non-skin) cancer among women in the United States, it is not surprising that many individuals with breast cancer will develop melanoma (the deadliest form of skin cancer) and vice versa...recent studies exploring how often individual patients develop both cancers suggest that it [is] more than just coincidence: A recent study by Murphy, et al, for example, found that patients with either breast cancer or melanoma were almost four times more likely to develop the other malignancy than probability would lead researchers to expect. Specific causes linking the diseases may be in play, and genetic or environmental factors may also contribute. On the other hand, the association may at least partly result from more rigorous detection – in other words, a detection bias. This occurs when health care providers who carefully monitor cancer patients detect a second cancer that might otherwise have been missed.”

Also: “Sometimes cancer cells can start growing in the skin. This is not the same as having skin cancer, melanoma, or cutaneous T cell lymphoma (a type of lymphoma that affects the skin). The secondary cancer may start to grow on or near an operation scar where the primary cancer was removed. Or sometimes secondary skin cancers can grow in other parts of the body.

A secondary skin cancer looks like a pink or red raised lump (a bit like a boil). Skin nodules can be treated. It is important to tell your doctor if you think you have one, because if it is not treated, it may become ulcerated [has a ‘cauliflower’ look to it; also it can be weeping].”

So it appears that breast cancer CAN spread to the skin – yet it doesn’t seem to be a common occurrence. I had a bit of trouble even finding places where the two kinds of cancers were linked. That doesn’t make it comforting – just one less-likely thing to worry about.
