World Cancer Day, February 4th - Early detection of Cancer can lead to Improved outcomes & Cure.

Cancer is a large group of diseases that can start in almost any organ or tissue of the body when abnormal cells grow uncontrollably, go beyond their usual boundaries to invade adjoining parts of the body and/or spread to other organs. The latter process is called metastasizing which is a major cause of death from cancer. A neoplasm and malignant tumour are other common names for cancer.

Cancer is the second leading cause of death globally, accounting for an estimated 9.6 million deaths, or one in six deaths, in 2018.

  • Lung, prostate, colorectal, stomach and liver cancer are the most common types of cancer in men.
  • While breast, colorectal, lung, cervical and thyroid cancer are the most common among women.

The cancer burden continues to grow globally. Many health systems in low & middle income countries are least prepared to manage, and large numbers of cancer patients globally do not have access to timely quality diagnosis & treatment.

In countries where health systems are strong, survival rates of many types of cancers are improving thanks to accessible early detection, quality treatment & survivorship care.

Between 30% & 50% of cancer deaths could be prevented by modifying/avoiding key risk factors & implementing existing evidence-based prevention strategies. The cancer burden can also be reduced through early detection of cancer and management of patients who develop cancer. Prevention offers the most cost-effective long-term strategy for the control of cancer.

If following key risk factors can be avoided/modified, One can help prevent cancer:

  • avoid tobacco use, including cigarettes and smokeless tobacco
  • maintain a healthy weight
  • eat a healthy diet with plenty of fruit and vegetables
  • exercise regularly
  • limit alcohol use
  • practice safe sex
  • get vaccinated against hepatitis B and human papillomavirus (HPV)
  • reduce exposure to ultraviolet radiation and ionizing radiation (occupational or medical diagnostic imaging)
  • avoid urban air pollution and indoor smoke from household use of solid fuels
  • get regular medical care
  • some chronic infections are also risk factors for cancer. People in low and middle-income countries are more likely to develop cancer through chronic infections.

Cancer is more likely to respond to effective treatment when identified early, resulting in a greater probability of surviving as well as less morbidity & less expensive treatment.

There are two distinct strategies that promote early detection:

  • Early diagnosis identifies symptomatic cancer cases at the earliest possible stage
  • Screening aims to identify individuals with abnormalities suggestive of a specific cancer or pre-cancer who have not developed any symptoms & refer them promptly for diagnosis & treatment.

Treatment options include surgery, cancer medicines and/or radiotherapy, administered alone or in combination. A multidisciplinary team of cancer professionals recommends the best possible treatment plan based on tumour type, cancer stage, clinical and other factors. The choice of treatment should be informed by patients preferences & consider the capacity of the health system.

Palliative care, which focuses on improving the quality of life of patients & their families, is an essential component of cancer care.

Survivorship care includes a detailed plan for monitoring cancer recurrence & detection of new cancers, assessing & managing long-term effects associated with cancer and/or its treatment, & services to ensure that cancer survivor needs are met.
