7. Changes in bowel or bladder habits
Sudden constipation, diarrhea, blood in the stool, or changes in urinary frequency can be signs of colon, bladder, or prostate cancer.
8. Difficulty swallowing
Difficulty swallowing, the sensation of having something stuck in the throat, or frequent choking may be related to tumors of the esophagus or throat.
9. Frequent infections or slow healing
If the immune system is weakened by cancer cells, wounds take longer to heal and infections are more frequent. Leukemia and blood cancers often present this symptom.
10. Abnormal bleeding or discharge
Any unexpected bleeding, such as coughing up blood, blood in the urine, or abnormal vaginal bleeding, should never be ignored. It is a common early sign of cancers of the reproductive organs, bladder, or digestive tract.
