Cancers are a group of hundreds of different diseases and affect various organs of the body. Cancer symptoms depend on the stage of cancer, the grade of cancer, whether it has spread to other organs, the general health, age and condition of the patient and numerous other factors.

Types of cancer symptom

Local symptoms

This includes the symptoms at the primary site of cancer. This may be a lump or tumor, pain, bleeding, ulcers or sores over the skin, pressure over the surrounding organs, hoarseness or cough that does not go away, obvious changes in a wart or a mole, changes in bladder or bowel habits,  difficulty in swallowing etc.

Systemic symptoms

This includes symptoms of the generalized body as a whole. Most of these are common for all types of cancer. These include weight loss, poor appetite, fatigue and wasting (known as cancer cachexia), excessive sweating especially at nights (night sweats), hormonal changes, anemia, bleeding tendencies due to deficiency of platelets (thrombocytopenia) etc.

Symptoms of spread of cancer or metastasis

This includes swelling of the nearing lymph nodes, cough, bleeding on coughing or hemoptysis (as seen in spread of the cancer to lungs), bone pain (as seen in spread of the cancer to bones), convulsions and neurological symptoms (as seen in spread of the cancer to brain), jaundice and abnormal liver function tests (as seen in spread of the cancer to liver) etc.
