What is the Soft and hard lump in my right hand under the skin

The majority of lumps that appear on your body are harmless, especially the kind that feel soft and roll easily (lipomas).

Most lumps and swellings are benign (not cancerous). In general, when a lump or swelling appears suddenly (over 24 - 48 hours) and is painful, it is usually caused by an injury or an infection.

If the lump comes on slowly over several days or weeks and does not hurt, it may be a tumor.

Check with your doctor for sure.
