Is it a sign of some kind of cancer.reply AS SOON AS POSSIBLE.  <response>: Thanks for asking in Chat Doctor forum In short: As pr your description it seems like a boilExplanation: A boil can get reduced after medication. And clot need not require medication. So, be cool frequent boils can appear in that place. Please avoid alcoholsmoking if you are into it. Then change your position while seated frequently to avoid this. I dont think it is cancer. Please visit a doctor if you have doubts.
