<s>[INST] Hello Sir, Today when i rubbed the side of my stomach , just above my hips i found a small knot or lump kind of marble shaped tiny ball inside, when i tried to push it, there was some small pain. Im afraid it might be cancer or tumor . However if i dont touch it im not having problem, What should i do next, is it any cause of concern. God bless you. Best Regards [/INST] Hello! Thank you for the query. First you should know that usually cancer in such area does not cause acute pains for a long time. If this lump is near groin region it can be an inguinal hernia. It can get bigger while standing and coughing. If so, surgery can fix it. Such painful lump can be also sebaceous cyst. This is benign soft tissues lump which get painful if it gets inflamed. IT can be also removed with surgery. The best way to have it diagnosed is to perform ultrasound of this area. Hope this will help. Regards. </s>
