Cancer affects one out of every three people in the United States. Cancer has most likely affected you or someone you know. Here is some information to help you understand cancer better. You are made up of trillions of cells that grow and divide as needed throughout your life. Cells usually die when they become abnormal or old. Cancer develops when something goes wrong in this process and your cells continue to produce new cells while the old or abnormal ones do not die as they should. Cancer cells can crowd out normal cells as they grow out of control. This makes it difficult for your body to function normally.

The Meaning of Cancer:
Cancer is a disease in which certain cells in the body grow uncontrollably and spread to other parts of the body. Cancer can begin almost anywhere in the human body, which is made up of trillions of cells. Human cells normally grow and multiply (a process known as cell division) to form new cells as the body requires them. Cells die when they become old or damaged, and new cells replace them.

When this orderly process fails, abnormal or damaged cells grow and multiply when they should not. These cells can combine to form tumours, which are tissue lumps. Tumours may or may not be cancerous (benign).

Cancerous tumours invade nearby tissues and can travel to distant locations in the body to form new tumours (a process called metastasis). Cancerous tumours are also known as malignant tumours. Many cancers form solid tumours, but blood cancers, such as leukaemia, do not.

Benign tumours do not invade or spread into nearby tissues. When benign tumours are removed, they usually do not recur, whereas cancerous tumours occasionally do. However, benign tumours can grow to be quite large at times. Some, such as benign brain tumours, can cause serious symptoms or be fatal.

The Differences between Cancer and Normal Cells:

Cancer cells are distinct from normal cells in numerous ways. Cancer cells, for example:

• grow in the absence of signals instructing them to do so. Normal cells only grow in response to such signals.

• disregard signals that normally instruct cells to stop dividing or die (a process known as programmed cell death, or apoptosis).

• spread to other parts of the body by invading nearby areas. Normal cells stop growing when they come into contact with other cells, and the majority of normal cells do not move around the body.

• direct the growth of blood vessels towards tumours. These blood vessels deliver oxygen and nutrients to tumours while also removing waste.

• avoid the immune system. Normally, the immune system eliminates damaged or abnormal cells.

• deceive the immune system into assisting cancer cells in their survival and growth. Some cancer cells, for example, persuade immune cells to protect the tumour rather than attack it.

• accumulate multiple chromosomal changes, such as chromosome duplications and deletions. Some cancer cells have twice as many chromosomes as normal.

• require different nutrients than normal cells. Furthermore, some cancer cells generate energy from nutrients in a different manner than most normal cells. This allows cancer cells to grow faster.

How does cancer spread?

As a cancerous tumour grows, cancer cells may be transported to other parts of the body via the bloodstream or lymphatic system. Cancer cells grow and may develop into new tumours during this process. This is referred to as metastasis.

Lymph nodes are frequently the first site of cancer spread. Lymph nodes are small, bean-shaped organs that aid in the fight against infection. They are found in clusters throughout the body, including the neck, groin area, and under the arms.

Cancer can also spread to other parts of the body via the bloodstream. The bones, liver, lungs, and brain are examples of these organs. Even if the cancer spreads, it is still named after the location where it first appeared.

Greetings. We are organizing an in-person CME/CPD accredited The 13th Emirates Pathology, Digital Pathology & Cancer Conference, Which is scheduled to hold December 15-17, 2023, in Dubai UAE & Online. And we invite you to attend as a speaker/listener/poster. Please let me know if you are interested.
