question: I have a hard lump on my collar bone just below my throat on the right side near the center. Notice it about a month ago. No weight gain or loss. Very noticeable by sight. About 1 in diameter. I am a 64 year old male, very active with Martial Arts, Stand up Paddle surfing, and golf. My right shoulder is pretty torn up. I ve been told I need surgery. Putting it off as long as possible,.
