Hi, i have found a lump on my right testical, that i have noticed this past few months, its attached to the side of my testical and is about a pea sized lump that is sore to touch.. it is only felt, you can not see it sticking out of my sack. Somedays it hurts without it being touched. I researched cancerous lumps, and they seem to be small numerous lumps that are visible to see sticking out the sack. Should i get this checked? I have a recent history of cancer in my family, could this lump be cancerous? Thanks
