Difficulty swallowing food, the feeling of having something stuck in the throat, or frequent choking may be linked to esophageal or throat cancer.

9. Frequent infections or slow healing
If the immune system is weakened by cancer cells, wounds take longer to heal and infections are more common. Leukemia and blood cancers often present this symptom.

10. Abnormal bleeding or discharge
Unexpected bleeding, such as coughing up blood, blood in the urine, or unusual vaginal bleeding, should never be ignored. It is a common early sign of cancer of the reproductive organs, bladder, or digestive tract.

11. Night sweats and fever
Although fever often indicates an infection, recurrent night sweats and unexplained fevers may also be linked to blood cancers such as lymphoma or leukemia.

12. Bloating and abdominal discomfort
Persistent bloating, indigestion, or abdominal pain, especially if associated with loss of appetite, may be early signs of ovarian, stomach, or liver cancer.
