Signs and symptoms are both signals of injury, illness, disease – signals that something is not right in the body.
The following is a list of 5 most common signs of cancer.
1. Unusual bleeding or discharge
Unusual bleeding can happen in early or advanced cancer. Coughing up blood may be a sign of lung cancer. Blood in the stool (which can look like very dark or black stool) could be a sign of colon or rectal cancer.
2. Unexplained, significant weight loss
One of the most common presenting complaints in people with cancer is unexplained weight loss. Some people report suddenly dropping two to three clothes sizes.
3. Excessive tiredness
This can be due to higher metabolic demands on the body because of the high energy requirements of cancerous cells. Tiredness that does not get better with rest is a reason for concern. Some cancers may cause blood loss (like gastrointestinal tract cancers) which can also cause tiredness.
4. Cough that doesn't go away
A cold or the flu can make you hack away, but it's also a potential symptom of lung cancer, along with red flags like chest pain, weight loss, hoarseness, fatigue, and shortness of breath. See your doctor if you can't seem to shake it, especially if you're a smoker.
5. Skin changes
A telltale sign of skin cancer is a growth that starts to look different or a sore that doesn't heal.
