Sometimes, cancer develops silently. It makes no noise and shows no obvious signs. However, some subtle signs can be cause for concern.

Breathing difficulties or wheezing : these symptoms are usually associated with asthma or other health problems, but they can also indicate lung cancer.
Frequent infections or recurring fevers : Some forms of leukemia weaken the body’s defenses, leading to more frequent infections.
Persistent fatigue is a common symptom. However, if it does not disappear and no apparent cause is found, it is best to consult a doctor.
Immediate feeling of fullness : Feeling satiated after only a few bites may be linked to ovarian cancer.
Difficulty swallowing : this could indicate throat cancer, or even lung cancer.

Some signs are more specific and visible, but are often explained by a simple temporary imbalance.
- Blood in the rectum or in the stool : a warning sign of colon cancer.
- Swelling of the neck, armpits and groin : enlarged lymph nodes may indicate a dysfunction of the lymphatic system.
- Abnormal bruising or bleeding : This is sometimes associated with a decrease in the number of platelets in certain types of blood cancers.
- Persistent swelling : In women in particular, this may indicate ovarian cancer.
- Unexplained weight loss : often associated with cancer of the digestive system or liver.
