Paralysis also known as “Plegia” is a kind of chronic disease in which nervous system does not working properly. Paralysis attacks occur when a person is unable to move a certain part of the body; during a paralysis attack, there is a disconnection of the body from the brain. Paralysis is usually of two kinds- partial or complete. Paralysis can affect either one or both sides of the human body. In some cases, just one area of your body gets affected, while in some other cases it can be widespread. When paralysis hits the lower half of the human body, such as both legs, it is referred to as paraplegia. When paralysis hits arms as well as legs, it is referred to as quadriplegia. In the majority of cases, paralysis happens because of strokes or any kind of injury like an injury to the spinal cord or a broken neck.

Cancer can develop anywhere in the body. It starts when cells grow out of control and crowd out normal cells. This makes it hard for your body to work the way it should. For many people, cancer can be treated successfully. In fact, more people than ever before lead full lives after cancer treatment. The cells in our bodies all have certain jobs to do. Normal cells divide in an orderly way. They die when they are worn out or damaged, and new cells take their place. In cancer, the cells keep on growing and making new cells. They crowd out normal cells. This causes problems in the part of the body where the cancer started. They can also spread to other parts of the body. Some cancers grow and spread fast while others grow more slowly. Cancer is a broad term. It describes the disease that results when cellular changes cause the uncontrolled growth and division of cells.
Certain forms of cancer result in visible growths called tumors, while others, such as leukemia, do not.
Most of the body’s cells have specific functions and fixed life spans, cell death is part of a natural and beneficial phenomenon called apoptosis.
A cell receives instructions to die so that the body can replace it with a newer cell that functions better. Cancerous cells lack the components that instruct them to stop dividing and to die.
As a result, they build up in the body, using oxygen and nutrients that would usually nourish other cells. Cancerous cells can form tumors, impair the immune system and cause other changes that prevent the body from functioning regularly.
Cancerous cells may appear in one area, and then spread via the lymph nodes. These are clusters of immune cells located throughout the body.

Gallstones are hardened deposits of digestive fluid that can form in your gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder holds a digestive fluid called bile that's released into your small intestine. Gallstones range in size from as small as a grain of sand to as large as a golf ball. Some people develop just one gallstone, while others develop many gallstones at the same time.People who experience symptoms from their gallstones usually require gallbladder removal surgery. Gallstones that don't cause any signs and symptoms typically don't need treatment.
