While cancer is a frightening and overwhelming diagnosis, treatments and survival rates have improved drastically over the years. Thanks to the advancements in medical technology, we have a better understanding of how cancer works, leading to better methods for diagnosing and treating it. In this blog post, we will explore the realities of dealing with cancer and the breakthroughs that have been made in recent years to help those who are battling it. We will take a look at some of the latest treatments being used, as well as how medical professionals are working together to find new ways to fight this deadly disease.
why celebrated cancer day
Cancer is a disease that affects millions of people around the world. It is a leading cause of death in many countries, and the incidence of cancer is increasing every year. Cancer Day is an opportunity for people to come together to raise awareness about cancer and to show their support for those affected by the disease.
There are many reasons why Cancer Day is celebrated. One reason is to promote cancer awareness. Many people do not know enough about cancer, and this day provides an opportunity to learn more about the disease. It is also a chance to remember those who have lost their lives to cancer and to show support for those who are battling the disease. Finally, Cancer Day provides an opportunity for people to unite against a common enemy – cancer. By working together, we can make a difference in the fight against this deadly disease.
history of cancer
The word cancer is derived from the Latin word for crab, which was first used by Hippocrates in the 5th century BC to describe tumors. The term cancer then referred to any malignant growth or tumor. In the 19th century, scientists began to develop a more precise understanding of how cancers form and grow. Theodor Schwann and Rudolf Virchow, working independently, provided the first detailed descriptions of cells, which are the basic units of all living things.
In 1838, Matthias Jakob Schleiden concluded that all plants are made up of cells. In 1855, Rudolf Virchow postulated that all cells come from other cells through cellular division. Together, these two discoveries helped scientists understand that cancer is a disease of cells gone awry.
Over the next few decades, scientists made major advances in understanding cancer at a molecular level. In 1858, Swiss physician Friedrich Miescher isolated a substance he called nuclein from human pus-filled Band-Aids® he had collected from local surgical wards. Nuclein turned out to be made up of two parts: nitrogenous bases (which we now call DNA) and phosphate molecules (which we now call RNA).
In 1944, American biologists Oswald Avery, Colin MacLeod, and Maclyn McCarty showed that DNA is responsible for transforming one type of bacteria into another. This was the first evidence that genes—the units of inheritance—are made of DNA.
cause of cancer
Cancer is caused by the abnormal growth of cells in the body. These cells can grow and divide out of control, forming tumors. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells become old or damaged, they die, and new cells take their place.
However, sometimes this orderly process goes awry. The genetic material (DNA) of a cell can become mutated, or changed. These changes are called mutations. Mutations can occur spontaneously or be caused by exposure to outside agents called mutagens (such as certain chemicals or radiation).
Most mutations are harmless; however, some mutations can cause the cell to become cancerous. When cancerous cells grow out of control and crowd out normal cells, it forms a tumor. Tumors can be benign (not cancerous) or malignant (cancerous). Benign tumors do not spread to other parts of the body and are rarely life-threatening; malignant tumors do spread and are often life-threatening.
