Why cancer is on the rise
A CT Scan machine at the regional Uganda cancer institute in Gulu | Joseph Omagor

Cancer as a disease is on the rise due to various factors. Some of the reasons include:

1. Aging Population: As the global population ages, the risk of developing cancer increases. Cancer is more common in older individuals, and with people living longer, the incidence of cancer is also rising.

2. Lifestyle Factors: Unhealthy lifestyle choices such as smoking, poor diet, lack of physical activity, and excessive alcohol consumption can increase the risk of developing cancer. These factors are becoming more prevalent in modern society, contributing to the rise in cancer cases.

3. Environmental Factors: Exposure to carcinogens in the environment, such as pollution, radiation, and chemicals, can also play a role in the development of cancer. With industrialization and urbanization, people are increasingly exposed to these harmful substances.

4. Genetic Predisposition: Some individuals may have a genetic predisposition to certain types of cancer, which can increase their risk of developing the disease. As genetic testing becomes more common, more people are discovering their genetic susceptibility to cancer.

5. Improved Detection and Diagnosis: Advances in medical technology have led to better detection and diagnosis of cancer. As a result, more cases of cancer are being identified at earlier stages, leading to an apparent increase in the number of cancer diagnoses.

It's important to note that while the incidence of cancer is rising, advancements in cancer treatment and research are also improving survival rates and quality of life for cancer patients.
