Chemotherapy is a systemic therapy; this means it affects the whole body by going through the bloodstream. The purpose of chemotherapy and other systemic treatments is to get rid of any cancer cells that may have spread from where the cancer started to another part of the body.
Chemotherapy is effective against cancer cells because the drugs love to interfere with rapidly dividing cells. The side effects of chemotherapy come about because cancer cells aren’t the only rapidly dividing cells in your body. The cells in your blood, mouth, intestinal tract, nose, nails, vagina, and hair are also undergoing constant, rapid division. This means that the chemotherapy is going to affect them, too.
Still, chemotherapy is much easier to tolerate today than even a few years ago. And for many people it’s an important “insurance policy” against cancer or pre-malignancy recurrence. It’s also important to remember that organs in which the cells do not divide rapidly, such as the liver and kidneys, are rarely affected by chemotherapy. And doctors and nurses will keep close track of side effects and can treat most of them to improve the way you feel.
There are no strict guidelines as to how long Chemotherapy lasts, each individual is different. Depending on the risk of your molar pregnancy you will receive treatment for approximately 4-6 months if you respond well, but this can change on a weekly basis dependant on your blood count and hCG levels.
