Introduction:
Cancer is the world's second-largest cause of death, accounting for an estimated 9.6 million deaths (2018). The global cancer burden is rising day by day, and it results in enormous emotional, physical, and financial strain on individuals, their families, communities, and healthcare systems.
Many healthcare systems in very low, low, and middle-income countries are unprepared to deal with this cancer load, and a majority of cancer patients in the world lack access to timely diagnosis and high-quality treatment. Proper implementation of public health measures can help lessen the burden of cancer and improve the general well-being and health of individuals and communities.
How Does Cancer Impact Public Health?
Cancer constitutes an extensive group of disorders and it may begin in any organ or tissue of the body. It occurs when abnormal cells develop uncontrollably, invade neighboring tissues, or spread to other organs. Cancer is the most significant cause of chronic disease-related death in the world. Nearly ten million people die of cancer each year. While the worldwide cancer burden is increasing, at least one-third of cancers are avoidable, and many cases and deaths can be avoided with early detection and prevention.
Cancer and its treatment result in a depletion of economic resources and opportunities for patients, employers, families, and the community. These costs include financial losses, illness, poor quality of life, and early death.
Even though each patient and their family is affected by cancer in a distinctive manner, understanding the manner in which cancer affects large groups can provide important insights into the behaviors, policies, and programs that have a direct impact on the health of millions of people.
What Are the Public Health Strategies That Should Be Implemented to Reduce the Burden of Cancer?
Cancer is not only a disease that affects an individual; it has much more impact than a disease entity. Once an individual is affected by cancer, the entire family and society are affected in one way or another. Thus, cancer has a great impact on public health.
The national burden gradually grows due to the financial burden resulting from reduced productivity and the costs of disease and therapy, premature deaths, as well as the long-term impact of cancer and its complications and treatment on the quality of life of survivors. Additionally, as the population ages, the impact of cancer on public health will also increase exponentially.
More than 30 percent of cancers are preventable. Tobacco, obesity, inactivity, infections, alcohol, environmental pollution, occupational carcinogens, and ultraviolet radiation are risk factors for cancer. By applying evidence-based measures for cancer prevention, screening, early detection, therapy, and palliative care, cancer can be controlled and prevented.
1. Cancer Prevention:
-
The most essential thing that can be done to lessen the worldwide burden of cancer is to develop surroundings and communities that make it easier for people to adopt healthy behaviors and prevent cancer from occurring.
-
Risk factors like tobacco, physical inactivity, obesity, alcohol, infections, environmental pollution, occupational carcinogens, and UV (ultraviolet) radiation should be minimized.
-
It is also crucial to implement immunization programs against HBV (hepatitis B) and HPV (human papillomavirus) in groups that are at risk.
-
The global cancer burden may be reduced by reducing exposure to other carcinogens such as radiation, occupational carcinogens, and environmental pollution.
2. Early Detection:
-
Early cancer detection can greatly enhance results and lessen the burden of the disease.
-
Promoting cancer screening programs, training and educating the public about the value of early detection, and removing obstacles to screening should be the main goals of public health initiatives.
-
Early detection of cancer increases the likelihood that it will react to therapy, improving survival rates, reducing morbidity, and lowering overall treatment costs.
3. Palliative Care:
-
Palliative care is treatment or care that is provided to a patient to lessen their discomfort or pain rather than to try to cure them.
-
Palliative care, which is frequently provided in the terminal stages of cancer, gives patients and those close to them a higher quality of life.
-
Children and adults with advanced malignancies have an immediate need for access to pain management on a global scale. Less than ten percent of the world's total demand for palliative care is being satisfied.
4. Proper Treatment:
-
Another important aspect of lowering the burden of cancer is "treatment." For cancer patients, prompt and adequate therapy can enhance results and quality of life.
-
The primary goal of public health initiatives should be to guarantee that cancer patients have access to effective and reasonably priced therapies like surgery, chemotherapy, radiation therapy, and other types of treatments.
-
For many cancer patients, especially those in low- and middle-income nations, access to cancer therapy can be a substantial hurdle. Cancer treatment can sometimes be too expensive, forcing patients to choose between it and other necessities like food and housing.
-
Regardless of a patient's income or location, public health initiatives should concentrate on lowering the cost of cancer treatment and enhancing access to care for all patients.
5. Research:
-
Cancer research should be given top priority in public health policies to deepen knowledge of the illness, create potent treatments, and find novel preventative measures. It can be done by supporting fundamental, clinical, and translational research, and encouraging partnerships between academics, healthcare professionals, and community-based organizations.
-
Significant breakthroughs in cancer therapy, early detection, and prevention have resulted from advancements in the field of cancer research. Public health programs should prioritize funding cancer research to accelerate the understanding of the biology of cancer, the development of new treatments, and the improvement of outcomes for cancer patients.
Conclusion:
Cancer is a major public health issue. It has a significant impact on individuals, their families, and healthcare systems. A coordinated public health approach concentrating on prevention, early detection, treatment, palliative care, and research is needed to reduce the cancer burden. Recent advances in the field of medical science have come up with various techniques for the early detection of cancer and its risk factors.
Early identification of abnormal cell growth changes in the body and their effective treatment will decrease the progression of cancer and its complications. As ongoing research in the field of cancer treatment continues to advance, it is anticipated that in the future, cancer prevention and management will become simpler and more effective.
