Cancer is a serious disease where abnormal cells grow uncontrollably and may spread to other parts of the body. Early detection is very important for successful treatment. Common warning signs include unexplained weight loss, fatigue, lumps, or unusual bleeding. A healthy lifestyle can reduce cancer risk—avoid tobacco, limit alcohol, eat nutritious food, exercise regularly, and maintain a healthy weight. Regular medical check-ups and screenings help in early diagnosis. Treatment options include surgery, chemotherapy, and radiation therapy depending on the stage of cancer. Always consult a doctor if you notice unusual symptoms. Awareness, prevention, and timely care can save lives. �
