4. Lumps or Thickened Areas Under the Skin

A lump or thickening in the breast, testicle, or other areas of the body can be an early sign of cancer. For example, a lump in the breast may indicate breast cancer, while a lump in the testicle could point to testicular cancer. Cancerous lumps are typically hard and immovable, but they can vary in texture and location. While not all lumps are cancerous, it’s important to get any unusual growths checked out to rule out cancer.

5. Changes in Bowel or Bladder Habits

Changes in bowel or bladder habits can indicate cancer, particularly cancers affecting the digestive system or urinary tract. Colon or rectal cancer, for example, may cause diarrhea, constipation, or a change in the size and shape of the stool. Blood in the stool or urine can also be an early sign of colon, bladder, or kidney cancer. Similarly, frequent urination, pain during urination, or the feeling of not being able to empty your bladder completely can be warning signs of prostate or bladder cancer.

6. Persistent Cough or Hoarseness
