question: Hi, my boyfriend has a lump on his chest which has been there for over a week now. It is about 3.5 cm long and is slightly discoloured. It is also very painful when it is touched. i am very worried for him as he wont go see a doctor and because he just seems to think it willl dissapear and it isnt getting any better it is getting worse. any idea what it could possibly be? thanks.
