Hi,
First of all,cancer is rare at your young age and also it rarely hurts,but any lump under the armpit (axilla) is concerning.  It could be something as little as a cyst or inflamed hair follicle.About the lump on your upper thigh it's obviously an infection since puss comes out of it when squeezed.Please go see your doctor who can give you the proper medication for the infections and also do a clinical breast examination to make sure that the lump in your armpit is not something more serious.I hope that you will make the appointment pretty soon.Take care ...
