What is Cancer?
Cancer is a deadly disease which arises from the transformation of normal cells into tumour cells in a multi-stage process that generally progresses from a pre-cancerous lesion to a maligant tumour. According to World Health Organization, approximately 400,000 children develop cancer and cervical cancer is the most common in around 23 countries of the world. Moreover, cancer is one of the leading causes of death worldwide, accounting for the deaths of nearly 10 million people in 2022.
Types of Cancer
There are numerous types of cancer named for the area of the body they begin from. Some clinical terms are used for certain types of cancer such as carcinoma, sarcoma, leukaemia, lymphoma and myeloma. Some common types of cancer include cervical, prostate, lung, skin, colorectal and breast cancer.
Signs and Symptoms of Cancer
According to WHO, some common signs and symptoms of cancer include:
Unexplained weight loss
umps or growths on the body
Changes in skin
Changes in digestion
Causes of Cancer
Cancer is mainly caused by mutations or changes to the DNA in the cells. Some external factors include physical carcinogens such as ultraviolet radiation, chemical carcinogens such as components of smoke, alcohol and biological carcinogens such as viruses or bacteria.
Risk Factors of Cancer
Some risk factors may contribute to the development of cancer in an individual or put them at a higher risk of getting prone to cancer. According to Healthline, these risk factors include tobacco use, exposure to air pollution, radiation, lack of physical activity, alcohol consumption, infections by certain viruses, and an unhealthy diet.
Early detection of cancer is highly necessary to provide effective treatment to the patient. As per WHO, there are two components of early detection which include early diagnosis and screening.
Early detection of cancer can help in better responses to the treatment and increased chances of survival. The early detections include three components which include:
1. Awareness of the symptoms, types of cancer, the importance of medications
2. Access to clinical evaluation
3. Timely treatment services
Screening to detect cancer is very essential. Screening is done with the aim to identify people with specific cancer or pre-cancer. With screening, abnormalities can be identified and it helps in suggestions of effective treatments and diagnoses. The screening programmes are based on age and risk factors. Some screening methods include HPV tests and mammography screening.
