Oral cancer: You need to see a dentist to evaluate any wounds or sores in your mouth that do not heal within 7-10 days. Also talk to your dentist about why you are chewing on the inside of your mouth, and what can be done to help you stop this habit.
Dr. Louis Gallia
Oral and Maxillofacial Surgery 45 years experience
Unlikely: Unlikely. Stop chewing. If abnormality persists, see oral surgeon or ENT doc.
Dr. Keith Hollander
Dentistry 36 years experience
Its rare: Its rare that the trauma of chewing would cause oral cancer. It will cause the overgrowth of a white line (called the linea Alba) of keratinized epithelium. This is like a callous that looks white because it is always wet.

Cancer risk: Repeated irritation can cause adverse tissue changes. Irritation can be mediated with dental care. Reason behind your pernicious habit can be mediated with behavior modification or therapy. Don't be scared. Get professional help. See a Dentist, have your tissues examined, and frankly discuss your problem with him/her.
Dr. Robert Douglas

An Oral: Cancer screening should be part of evert dental exam. It's very unlikely but possible to cause mouth cancer with constant irritation for many years. See your dentist to know for sure.

How can you get bladder cancer if you're constantly urinating?

In other ways.: The development of bladder cancer has little to do with the frequency of urination. It has everything to do with changes to the lining of the bladder, mostly due to exposure to toxins in the urine, such as from cigarette smoke & industrial chemicals. Inherited genetic factors play a role as well. For those that have developed bladder cancer, one of the symptoms can be frequent urination.

Acne Therapy: Acne treatments work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection, reducing the inflammation or doing all four. With most prescription acne treatments, you may not see results for four to eight weeks, and your skin may get worse before it gets better. There are topicals like ziana and epiduo and oral medication like solodyn (minocycline). See your dermatologist.
