The REAL Cure for Cancer

If is not something common that could be checked and detected, then you will only know is cancer when is too late. Sorry to say it. Don't live your life in fear, enjoy your time on this planet. In a few days will be 3 years since I lost my mother. 
Some clues of late cancer that seems common in many people with cancer: 
- A flu like symptoms that keep reappearing. 
- You being sicker more often than before. (A talk about seasonal things) if you are sick 1-2 times max per year, anything above that may be odd, since your immune system could be weaker due cancer. 
- You have family history of cancer + above.
