<s>[INST] Well I had a limp on my penes near the base of the shaft, I looked for answers and may told me to pop it. So I did, It did not go away though, It became a scab. Im worried it may be penile cancer, Im 15 and circumcised, never had sex before. Any help? [/INST] dear,I would suggest to consult a local surgeon as a detailed clinical examination is must. No need to worry as prnile cancer does not present at this age and in this manner.we need to consider possibility of skin lesion or trauma injury. </s>
