According to global cancer statistics 2020(International agency for research on cancer) in 2020 there were about 19.3 Million new cancer cases worldwide and 10.0 million deaths due to cancer.
Deaths from cancer can be reduced by detecting cancer early but you have to know what the early symptoms are to be able to know when to contact a clinician for tests.
Below is a guide on symptoms of the most common cancers:
Cancer of the brain-Constant headaches six weeks+,vision impairment, imbalance walking,
Cancer of the breast-Breast lumps, continuous breast pain usually one side, enlarged glands usually in armpit, breast skin changes particularly dimpling and eczema around the base of nipple and blood from the nipple.
Lung Cancer-Chronic cough 3 weeks+,coughing up blood, breathing difficulties, weight loss.

Bladder Cancer-Blood in urine, persistent pain in the lower central abdomen, recurring urine symptoms eg frequency, pain passing urine, frequent urine infections.
Prostate Cancer-Poor urine stream needing to strain at urination or No symptoms at all so routine exam of the prostate is recommended in males of males ages 40years and above.
Cervical cancer-Bleeding from the vagina outside of normal menstrual period, bleeding after sexual intercourse, persistent abnormal vaginal discharge.
