Pain inside the right scapula is not necessarily cancer, but should be analyzed according to its accompanying symptoms. The most likely cancers that cause scapular pain are scapular bone tumor, liver cancer and lung cancer. Bone tumor will have symptoms such as obvious local swelling, rapid growth of mass, pressure pain in scapula and worsening pain at night, and limited movement of scapula; liver cancer will have symptoms such as pain radiating from scapula, upper abdominal mass, persistent dull pain, swelling or stabbing pain in liver area, and reduced food intake; lung cancer will have symptoms such as cough, blood in sputum or hemoptysis, difficulty in breathing, and even vague or dull pain in chest, in addition to pain radiating from scapula. In addition to cancer, other causes of right scapular pain include cervical spondylosis, frozen shoulder and other neck and shoulder problems, symptoms such as stiffness of neck and shoulder muscles, numbness of upper limbs or arms not daring to rotate internally or abduct, and obvious restriction of movement; myofasciitis of the back of the shoulder, which can also lead to pain in the scapular region; gallbladder stones or cholecystitis, which can cause symptoms such as abdominal distension or vomiting, aggravation after eating greasy food, and noisy stomach discomfort. When there is pain in the right scapula, you can go to orthopedics or pain department for X-ray examination to clarify the cause, and if necessary, MRI can be performed to clarify the presence of tumor.
