Medications are critical for treating diseases, reducing pain and improving mood and attention among other things. Can you describe several examples of diseases and the ways in which medicines are helping to treat these diseases?
Diabetes results from loss of the ability to regulate blood sugar levels. Insulin decreases blood sugar levels by helping the sugars move into tissues and out of the blood. Cancers result from cells that begin to divide rapidly and spread into other tissues of the body. Radiation therapy targets cancer cells by using energy that can enter the cells and damage the cancer cells, ultimately killing them in a particular location. Attention Deficit Disorders result in a lack of focus and often an inability to complete a given task. Stimulants such as Adderall increase focus and attention helping a patient complete projects and carry out everyday responsibilities.

Everyday we hear about illnesses and diseases that we currently are unable to effectively treat. Cancer is a widespread, aggressive and often extremely challenging disease to clinically address and cure. Despite our ability to effectively identify and classify cancer cells, we are frequently unsuccessful when trying to treat patients with a particular cancer. Provide a brief insight or two as to why cancer is so difficult to fight and treat.
Below are several characteristics of cancer cells that make the disease so challenging to treat. Cancer cells are often hard to eradicate because they divide very rapidly and many can then spread throughout the body in a virtually uncontrolled manner. Cancer cells often differ dramatically even within the same type of cancer. Cells may differ in shape, types of proteins in the cell or on the surface or in the ability of the cells to form tissues and interact with other cells. Cancer is initiated in a single cell. Even following treatment, cancers can return due in part to the remaining cells, unharmed by treatments, once again dividing and spreading. Many other answers may be appropriate for this example!
The death of cells within an organism is typically interpreted to be a sign of old age, disease or injury. Can you think of an example where the death of cells actually plays a positive and necessary role?
During development of an organism, cells are often produced in excess to ensure an adequate number exist to form body structures with proper anatomical specialization. Programmed cell death (PCD) is a deliberate developmental mechanism that removes unneeded cells leaving only the necessary and essential cellular structures.
