Symptoms of Cancer
Symptoms of cancer vary depending on the type, location, and stage of the disease. While some cancers present with clear signs early on, others remain silent until they are advanced. Common symptoms of cancer include unexplained weight loss, fatigue, persistent pain, skin changes, and abnormal bleeding.
One of the most common warning signs is unexplained weight loss. Losing more than 5–10% of body weight without dieting or increased exercise could signal an underlying issue, including cancer.
Fatigue that doesn’t improve with rest is another frequent symptom. Cancer-related fatigue is often persistent and can interfere with daily activities.
Pain can be an early sign of some cancers. For example, headaches that don’t go away could be linked to brain cancer, while back pain may signal spinal tumours or pancreatic cancer. Persistent pain without a clear cause should always be investigated.
Skin changes are also important indicators. These include new moles, changes in existing moles, or sores that don’t heal. Jaundice (yellowing of the skin or eyes) may suggest liver or pancreatic cancer.
Lumps or swellings in the breast, testicles, neck, or underarms may indicate a tumour. These should always be checked, even if painless.
Other key symptoms:
- Persistent cough or hoarseness
- Difficulty swallowing or persistent indigestion
- Changes in bowel or bladder habits
- Unusual bleeding, such as blood in urine, stools, or from the vagina
- Frequent infections or fevers, which may be signs of leukaemia or lymphoma
Symptoms of Cancer
Because these symptoms can also result from non-cancerous conditions, they don’t always mean cancer is present. However, persistent or unexplained symptoms should never be ignored.
Recognising symptoms of cancer early increases the chance of successful treatment. Regular check-ups and knowing your body well can make a life-saving difference.
