### input:
Hi, I m a 40 yr old white female. About 3 or so yrs ago I found a small lump (about the size of a nickel) on my back, just above my tailbone. I showed it to my chiropracter and my PCP; both said it was a sebaceous cyst and nothing to worry about. Since that time, my weight has been up and down, from a high of 470 to a low of 316. Currently, my weight is about 420 (and hopefully will continue to reduce!). This cyst has gotten bigger. About a year ago, I consulted w/ a surgeon to see about getting it removed. He didn t think it was cancer, but said it should come off. The appointment was made, but before I could get it done, I lost my insurance. Now, it is a little bit bigger ( I refer to it as my tail ) and developed a raw spot and started to bleed. Hubby patches me up and I m ok. However, it has bled again at least 4 times. Each time, we get it to stop, use nuskin spray and gauze pads and tape. I can t keep doing this forever, but I m w/out insurance and we ve already got a ton of credit card debt we re dealing with. (BTW, we make too much for public assistance). Could it be cancer? A girl I met online said she had the same thing happen to her, but hers was something that happens in less than 5% of PREGNANT women. As far as I know, I am not pregnant. Help! I am very worried. Thank you for your help.

### output:

Hi.it is best that you go back to your doctor, preferably a general surgeon, for clinical evaluation, especially if you notice it to be increasing in size and is bleeding. It could be a simple cyst (gelatinous or sebaceous type), but other tumor lesions must also be ruled-out. Diagnostics, such as imaging and a possible biopsy, may be recommended. Management (medical and/or surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
