What is Chemotherapy and how does it influence your eye ?

Chemotherapy can destroy cancer cells that have metastasized, or spread to parts of the body far away from the primary (original) `tumor`. More than 100 chemotherapy drugs are used in various combinations. `Combination` of chemo drug with hosts of other drugs is called as `Combination chemotherapy`! With such combination is meant the `Killing of Multiple diseases` at the same time rather than searching upon a specific medicine to kill only a single aspect of the concerned disease?
`Your doctor and you will decide what drug or combination of drugs, what dosages, how it will be given, and what frequency and length of treatment are best suited for you. All of these decisions will depend on the type and location of the cancer, the extent of its growth, and how it is affecting your normal bodily functions and overall health`. The name should suggest: `Aspirin or Penicillin`! Two other medical terms often used to describe cancer chemotherapy are anti-neoplastic (meaning anticancer) therapy and cyto-toxic (cell-killing) therapy.
Detailed Guide: Treatment stage-by-step
`Chemotherapy or EYE Surgery` :
It’s done to ensure whether there exists an `Eye Tumor` inside an eye or not without the presence of Tumor it is not done in a first hand. Another important factor is whether the cancer has affected one or both eyes. Generally when one eye is affected, doctors are less reluctant to recommend surgery because the other eye can be preserved. When both are affected, then all efforts are made to save some vision, at least in one eye through `Chemotherapy`!
`Side effects of Chemotherapy` :
1) `Reduction in the number of blood cells (Anemia);
2) `Feeling Exhausted(Drowsiness/Whacked Out); Sick
3) `Diarrhea`;
4) `Sore mouth and mouth ulcers;
5) `Hair loss and Thinning`.
`Eligibility Criteria` (Inclusion Criteria) :
Each clinical trial has certain conditions, or criteria, that patients must meet before they can enter the study. These are necessary to ensure that the study can answer the specific questions it was designed to answer. For cancer clinical trials, these criteria usually have to do with:
• The type of cancer a person has
• The stage (extent) of the cancer
• Previous treatments a person must or must not have had
• The length of time since a person last received treatment
• Results of certain lab tests
• The medicines a person is taking; Other medical conditions the person has
• Any previous history of another cancer
• A person’s activity level (also known as performance status)
• You complete treatment on the study.
• The treatment does not appear to be working for you.
• You have serious side effects while in the study.
• The study itself is stopped early because the treatment either has proven to be effective or has proven to be too harmful in other participants.
• You decide to leave the study; the reason for the study (what the researchers hope to find out)
• Alternative treatments that may be an option for you
• The design of the study (whether it is randomized, double blinded, etc.)
• How many and what types of tests and doctor’s visits are involved
• who is responsible for the costs of the clinical trial (tests, doctor’s visits, etc.) and for the costs if you need additional care as a result of the clinical trial
• A statement about how your identity will be protected
• A statement about the voluntary nature of the study and your right to leave the study at any time without fear of compromised care
