Fluorouracil skin cancer cream for solar keratosis

Carac is a skin cancer cream containing 0.5% fluorouracil. It is mostly used to treat solar keratosis, also called actinic keratosis.

It is sometimes used to treat basal cell skin cancer when it is in the very beginning stage.

So what is actinic keratosis? ...and what fluorouracil does

Actinic keratosis and solar keratosis are actually the same thing and it is nothing more than sun damage. If you have a small amount of it, your dermatologist will probably spray it with liquid nitrogen which freezes it. In several days it will drop off. You Can Read More About Actinic Keratosis Here.

When actinic keratosis covers a large area or there are many small spots of it in an area, a dermatologist may prescribe a skin cancer cream containing fluorouracil. Two of these creams, that I know of, are Carac and Efudex.

Efudex is the stronger of the two and is more invasive to your whole body and could cause nausea along with other symptoms shared with Carac. Efudex is applied twice a day and Carac only needs to be applied once a day and they both produce the same results, Carac being friendlier.

The symptoms they have in common are they both cause your skin to turn red with irritation and erosion. The actinic keratosis cells are being destroyed.

Carac cream is often prescribed by dermatologtists to destroy and eliminate the sun damaged skin. If the dermatologist prescribes Efudex, I would ask if Carac could be an option.

It takes a few days before the treated skin will start to turn red and some spots will turn a stronger red. These are the areas where the sun damage is more concentrated. You’ll gradually see parts of your skin come loose and start to flake off.

When you stop applying the chemotherapy cream and the solar keratosis spots have all flaked off, your skin will return to normal, soft and just as before.

You will not have any ugly damage left behind.

Have you ever used any chemotherapy skin cancer cream or has your dermatologist just prescribed some for you?

Hi! My name is Nick and I’m 56 yrs. old and this is part of my story. Let me tell you, I was like a lot of people out there and I had no idea that skin cancer was anything bad. I had Basal cell back in 2007, but that was no big deal and it was removed and that was the end of that. No one told me that it was a type of skin cancer (I looked it up on my computer). But still no big deal, it would not kill me.
But I did know the word "Melanoma"....." --by Nick

Bottom Line
The Weather Channel has done well posting this information and photos to help you spot skin cancer, including melanoma.
It can be hard to spot, even for a professional.
The bottom line is to get an expert's opinion about any suspicious mole or lesion on your skin. If necessary, get a second opinion  and/or request a biopsy. it’s always better to be safe than sorry.

Don’t put your very life at risk!
