What you described is not a sign of cancer. However, it is not feasible to provide a meaningful opinion without examining you. You can reduce your risk of cancer by adopting healthy habits: Eat a mostly vegetarian diet, avoid alcohol, tobacco and street drugs, avoid excessive exposure to sun, exercise 30 minutes/day, maintain healthy weight drink enough water so your urine is mostly colorless.

In that region there is muscle, spleen,colon,stomach& pancreas. Gas can accumulate there in the colon. Gastritis,( inflammation of stomach lining) can be a source of tenderness. After an exam by your MD you can be advised as to possible causes of tenderness & whether any testing or referral to a gastroenterologist would be advisable
