A cancer diagnosis will be given to more than 18 million people worldwide in 2020.
World Cancer Day is observed on February 4 each year and is a global effort to increase awareness of the prevention, detection, and treatment of one of the top causes of death worldwide.
The number of people who received a cancer diagnosis in 2020 was above 18 million. These cases affected 9.3 million men and 8.8 million women, respectively. Al Jazeera examines one of the biggest health issues in the globe in the following infographic series.
In what way does cancer grow?
Millions of billions of cells make up the human body. Cell division, which is the process of creating new cells, occurs every day. An ordinary cell grows first, then divides, and eventually dies.
The genetic mutations that cancer cells experience, on the other hand, cause them to divide uncontrollably. After that, these cells can travel to other body parts by invading surrounding tissues.
The size and location of the tumor are just two of many variables that affect how cancer develops, which is assessed in stages:
stages of a cancer
Stage 0: Abnormal cells are present but have not yet spread to the tissues close by.
Stage 1 (early stage): No lymph nodes or distant sites have been reached by the cancer, and it has not penetrated extensively into the tissues close by.
Stage 2 (localized): Tumor cells have deepened their infiltration into nearby tissues, but not into distant locations inside the body.
Stage 3 (regional spread): The cancer has penetrated more deeply into nearby tissues and reached lymph nodes, but it has not yet reached other parts of the body.
Stage 4 (far spread): Cancer cells have penetrated lymph nodes, other bodily regions, including organs, and possibly distant tissues in addition to the local tissues they were previously contained in. Advanced cancer is a common term for this stage.
forms of cancer that are more prevalent
Over 100 different forms of cancer exist, according to the National Cancer Institute in the US.
Bones, organs, and even the skin are all potential sites for cancer to develop. The organs or tissues where they begin are typically used to name the various cancer kinds.
In 2020, the World Health Organization estimates that breast and lung cancer will account for 12.5 percent and 12.2 percent, respectively, of all new cancer cases globally (WHO).
Among 2020, 15.4% of all new cancer diagnoses will be related to lung cancer, which is the most common type of cancer in men. The majority of new instances of cancer among women in 2020 will be breast cancer, which will account for nearly one-fourth (25.6%) of all new cases. How many individuals pass away from cancer?
Cancers don’t always result in death. It’s crucial to find and treat cancer as soon as it is discovered, though. Early cancer detection increases the likelihood that the disease will react to treatment and improves the prognosis.
Additionally to early detection, cancer screening is a successful method of spotting aberrant cells before they might develop into cancer. The likelihood of dying from cancer has been demonstrated to decrease with the use of a number of screening tests.
According to the Institute for Health Metrics and Evaluation, more than 10 million people worldwide died from cancer in 2019, making it the second biggest cause of death behind cardiovascular illnesses (IHME). 70 years of age or older accounts for over half, or 46%, of all cancer fatalities. commonest causes of cancer death
