Tingling can be a symptom and sign of cancer including breast cancer and brain cancer.

Costochondritis is inflammation of the cartilage which connects the ribs to your breastbone and can cause a sharp pain or numbness and sometimes tingling in or near the breast.
If the tingling is accompanied by other symptoms such as changes in breast appearance, lump in the breast, nipple discharge, heat, itching, redness, swelling or dimpling of the skin it could be a sign of breast cancer.
Brain tumors can cause numbness and tingling in the face, arms, hands, legs and feet.
This is because the brain plays a key role in feeling sensations throughout the body.
You should get emergency help or contact 911 or go to the hospital if you have have any weakness or are unable to move, along with numbness or tingling.
