hi my sister had a lump on her left butt cheeks couple years ago and took it for nothing,now it feel like its growing and its painful.doctor doesnt know what it is untill the cut it. have you any experience with that.what can it be? am scare for my sister
Hello! Thank you for the query.First do not be scared. From your description the lump is benign soft tissues lesion. The pain indicates some inflammation. If the lump is close to the butt crack, most probable reason if this lump is colonial cyst. This condition is caused by ingrown hair which irritates the tissues and leads to inflammation. If it's located in other part of butt, hair follicle inflammation or sebaceous cyst can be the case. The best she can do is to consult general surgeon. In case of any doubts, soft tissues' ultrasound can be done. Hope this will help. Regards.
