Early Cancer Symptoms: What to Watch For & When to See a Doctor

There is no one definitive first sign of cancer. Different types of cancer can present with a variety of symptoms, and some cancers may not cause any symptoms in the early stages. Some common signs and symptoms that can be associated with cancer include:

- A new or unusual lump or swelling

- Sudden or unexplained weight loss

- Fatigue

- Fever

- Persistent pain

- Changes in bowel or bladder habits

- Unusual bleeding or discharge

- Cough or hoarseness that doesn't go away

- Difficulty swallowing

- Persistent changes in skin color or texture

- Unexplained itching or rash

- Sores that do not heal

- Vision changes

- Headaches

- Swollen lymph nodes

It is important to note that these symptoms can be caused by a variety of conditions other than cancer, so it is not always possible to self-diagnose cancer. If you are experiencing any of these symptoms, it is important to see a doctor to determine the cause and receive appropriate medical care.
