My Mom has lumps on her back that seem to be dried skin. How do I get rid of them?

My husband is fair-skinned, was an outdoors man before sunscreens and has had multiple skin cancers[basal cell/squamous] - usually they are small lesions which bleed and then scab and then break off and bleed again when they are more advanced. Then the freezing done by the dermatologist may leave small white scars. If more than a keratosis, a biopsy may be taken. If in a sensitive place like the nostril and not caught early, it ended up with Moh's surgery (slicing off a thin piece at a time, checking for cancer cells and slicing some more until no more cancer cells are seen) and then a skin graft from behind the ear. I've been outdoors, too, but don't seem to get anything that needs to be frozen. He gets a full body check at least once a year.and visits in between for anything suspicious.

Let a dermatologist see her, and find out for sure what it is before doing anything else. Oils and creams won't hurt anything, but it may delay catching something serious.

This might be psoriasis and you could try an over the counter gel, but I would go to a dermatologist to find out what it really is.

Get to a dermatologist. It sounds like keratosis which are pre-skin cancer lesions which can be frozen with liquid nitrogen and are benign, but to make sure you need the dermatologist to review her largest organ - the skin.

I bought some Frankenscents oil and mixed it with a very high quality cold pressed olive oil because the lotions were absorbing into her skin as fast as I could apply them. It has worked much better than anything I have tried.
She loves it and says " Oh that feels sooo good."
It doesnt to me but some say that the frankenscents doesnt smell very good.

Clumps of dried skied provide an opportunity for MRSA to take hold and multiply. Apply baby oil and let it soak in. Like Jessie Belle said, gently exfoliate the dead skin. Don't expect to get it all off on the first try.
Mom needs help with bathing the areas she can't reach, like the back and the lower legs and feet. Don't use soap on dry skin, use a moisturizing wash like Alpha Keri, which comes in a Cream Wash, a Shower Oil, Lotion and Ointment. Readily available almost anywhere.

Gentle exfoliation. If they are simply dried skin, they won't cause problems. If the lumps are extensive, you may want to visit a dermatologist to get recommendations. Medicare will pay for a dermatologist if you live in the US. I think most elders can benefit greatly by having a yearly exam by a good dermatologist. The exams are so simple to do, and the doctors are good at finding carcinomas and other skin problems that are easily fixed. It is well worth the time and money, since skin ailments can be so problematical for elders.
