What skin cancer may look like:


These fun skin facts are interesting to read and learn. With skin being the largest organ of the body, it is important to know that skin cancer is ever increasing in numbers. The two most common skin cancers are basal cell and squamous cell carcinoma. Basal Cell Cancer accounts for more than 90% of skin cancers in the U.S. Melanoma is usually the most serious form of skin cancer because of its tendency to spread throughout the body quickly. Although skin cancer is more prevalent in light colored skin; it is important for ALL people to take it seriously. There are many characteristics and appearances of what a skin cancer looks like. It may appear as a flat red spot that is rough or scaly or an undefined area that appears.

The skin's sloughing cycle actually varies from person to person, but the process becomes slower as we age. So a younger person's skin may renew itself fully over the course of 10-14 days, but an older person's may take 28.

Esthetics Educator 5 years ago

Your facts are not all correct.

Also, some of the comments are not correct either. Your skin does, on AVERAGE, renew itself every 28 days, and slows down from there during the natural aging process.

Goosebumps, ARE NOT pimples. They are a reaction from the arrector pili muscle, a minute muscle attatched to the hair follicle that causes the hair to stand on end, to help retain body heat.

A pimple is skin and debris being retained in the follicle causing an infection and inflammation.

The two are very different things.

Please complete your research and check all your facts before posting things. These children doing school projects about the skin are going to read this and think you are 100% correct and you're not.
