Cancer is a prevalent disease worldwide. According to the World Health Organization (WHO), cancer is the second leading cause of death globally, accounting for an estimated 9.6 million deaths in 2018. The frequency of cancer varies by geographic region, age, gender, and other factors.
The occurrence of cancer is influenced by various risk factors, such as age, tobacco and alcohol use, diet and physical activity, exposure to carcinogens, family history of cancer, certain infections (such as human papillomavirus, hepatitis B and C), and genetic mutations.
The most common types of cancer globally are lung cancer, breast cancer, colorectal cancer, prostate cancer, stomach cancer, and liver cancer. However, the incidence and prevalence of specific types of cancer can vary depending on factors such as population demographics, lifestyle choices, and access to healthcare.
It’s important to note that cancer is a complex disease and ongoing research is being conducted to better understand its causes, risk factors, prevention, and treatment options. Early detection, lifestyle modifications, and appropriate medical care can play a significant role in managing cancer risk and improving outcomes for those affected by this disease.
