CLUES OF CANCER PROGRESSION

A. Bone metastasis

Bone metastasis indicates that cancer cells have started to spread from its original site to the bone. It is likely that most types of cancer can progress to this degree where it’s been able to spread, particularly cancers like that of the breast and prostate.

Bone metastasis may also occur in any bone but commonly does so in the spine, pelvis, and thigh area. It can also be an early sign for some types of cancer or can occur later after cancer treatment. The following are the symptoms:

(1) Joint pain or fractures;
(2) Bowel and urinary incontinence;
(3) Weakness in legs and arms; and
(4) High levels of calcium in the blood.
