Generally speaking, cervical cancer does not cause shoulder soreness, swelling and weakness, but the symptoms of cervical cancer include increased leucorrhea, abnormal vaginal bleeding and abdominal pain. The causes of shoulder soreness and body weakness may be related to physical exertion, frozen shoulder and cervical spondylosis. 1. Physical exertion: a short period of hard work can easily cause strain on the muscles of the upper arm, ligaments, fascia and other soft tissues, resulting in shoulder pain and swelling and weakness. 2. Frozen shoulder: Inflammation around the shoulder joint will lead to localized adhesions, causing limited movement around the shoulder joint and shoulder pain. 3. Cervical spondylosis: If the vertebral artery or other surrounding nerve roots are compressed, it will lead to damage to the nerves, which will cause abnormal local reactions, such as soreness and pain. Shoulder soreness and body weakness are not related to cervical cancer in general, but if patients have the above symptoms, they should pay great attention to them, and it is recommended that they go to professional hospitals as soon as possible, complete systematic examination under the guidance of doctors, clarify the causes of the disease, and receive correct and targeted treatment.
