Cyst problem?

ive had this cyst right in the middle of my chest for almost 3 years.. went to the doctor and he tried sticking a needle in it i guess to drain and no luck. he said it hardened. he ask if it bothered me and said no and he said wait and see if it goes away on its own... as of about a week ago it just started hurting and getting bigger and now i have a bruise color and is almost the size of a golf ball which was nowhere like this a week ago. it was the size of a small marble a week ago. i will definately go to the doctor but for now i need a little comforting on what it may be; like. ie. cancer which i hope not or which kind of cyst does anyone thinks it is. please help. im worried. im a male 28 yrs old....

Cyst problem?
It sounds just like a sebaceous cyst that has been irritated. Probably when the doctor tried to needle aspirate it, he set it off, and he may have ruptured a small blood supply nearby, which is why it's bruised. The doctor can remove it and hopefully solve your problem. Just leave it alone until you can get back to see him, don't mess with it because you certainly don't want to break it under the skin. But no, it doesn't sound like cancer at all. Think positive and quit thinking exotic.
Reply:Don't worry so...more then likely its just infected....they will either lance it to drain it and give you antibiotics or may even surgical remove it and biopsy it , Some people are just unlucky to get cyst...some times they don't case pain, but every thing you wrote tells me it's infected get it looked at ASAP because it can lead to more serious problem.
Reply:Probably just a cyst I had one on my back about 5 minutes and a surgeon can have it removed its no biggy. Mine turned purple and started hurting also. If it turns it just means its getting infected and need removed.
