Dear Cancer Patient/Caregiver,
Cancers are generally treated in 4 main ways Surgery, Radiotherapy, Chemotherapy, and Targeted therapy/Immunotherapy. This write up mainly focuses on chemotherapy to help you understand more about it, demystify the rumors and make your treatment journey as smooth as possible.
What is Chemotherapy ?

Who is a Medical Oncologist?
Why do I need chemotherapy?
How is chemotherapy given?
Chemotherapy is not a one-time thing like taking anti-malarial drugs, it’s a journey. It begins the day your oncologist recommends this treatment for you. He/she will explain why it’s needed, the combination of drugs to be used and the anticipated side effects. You will then sign a consent form similar to that you would sign before a surgical operation. Chemo usually takes place in an infusion centre, and in most cases as a day-case procedure meaning you will not be admitted to the in-patient wards. There are some chemos that require you to be admitted to hospital for a few days due to the nature the infusion.
Prior to the date scheduled, you will be required to do blood tests to assess your bone marrow, liver, kidney function. In most cases (not all), these are done prior to each session. Your doctor or nurse will review your results and you will only proceed if they are satisfactory. Your doctor/chemo nurse or pharmacist can determine this. The chemo nurse will then fix an IV canula on your hand which will be used to deliver the treatment. Some patients who require longer drips will use chemo-ports that are usually implanted under the skin below the collar bone prior to chemotherapy. Make sure you tell your chemo nurse if the drip IV cannula is painful swollen or burning so as to minimize chances of leakage. The line should flow with ease and without pain.
On the day start chemo (call it Day 1), your trained pharmacist will carefully reconstitute and prepare your chemotherapy drugs following the detailed instructions from your oncologist. Think of it like a chef following instructions from a food recipe. A recipe that is specifically written for by your oncologist. Your chemo nurse will then take over and begin the infusion process. The nurse is like your personal waitress. She/he will oversee the delivery. The whole team has to work together. First, you will receive what we call premedication which consists of a cocktail of drugs to counteract the effects of chemotherapy particularly nausea, vomiting and allergic reactions. This is like starter soup to warm you taste buds. After the first infusion you and receive the chemotherapy (main meal) which looks pretty much like any IV drug. Don’t be spooked if you find it covered with black bags. This is to protect it from UV light. You can eat before, during and after the drip. It is not painful. The nurse will monitor you. If you feel like itching, scratching, or chest tightness please alert your nurse immediately. This may be an allergic reaction. Most are mild and are treated easily allowing you to continue with the drip Once the drip is over you will receive some IV fluids (desert) to flush the system and then you'll be unplugged and you can go home. You will carry home tablets to swallow usually to counteract nausea and other acute reactions. Sometimes your doctor may prescribe for you immune boosting injections which you may receive for several days after chemotherapy.
Please make sure you note the date of the next cycle/session (usually 21 days later, may be shorter or longer). Please take note of all instructions given to you by your chemo nurse. You will be given a lab test form for the same blood tests to carry out before the second cycle/session. It is important to communicate to your doctor/nurse any side effects the fact you may experience so that they may be managed quickly as they appear and this is why Chemotherapy is more of a relationship more than a one-time procedure.
Why does chemo cause side effects?
Cancer cells are fast growing and that’s why we use chemotherapy to kill them. Because chemotherapy circulates throughout the whole body, it tends to harm other body cells that also grow quickly. These include hair, mucous membranes in the mouth and blood cells in the bone marrow. These effects are not universal and should not make you worry so much. Some chemotherapy drugs may affect cells of major organs like heart kidney, bladder and lungs . These are rare and tend to occur with very high doses. Your doctor will mention these to you in case it is relevant and take all necessary precautions.
What do you need to remember about chemo side effects?
Many times, you may have heard about a neighbor or relative who “suffered” throughout chemotherapy and experienced “very bad” side effects. Most of the time, this occurs because the treatment is not being monitored closely. Most patients’ usually “suffer” because of the cancer itself and not the chemotherapy. Constant communication with your doctor is key. Think of it as a relationship rather than just a one-time treatment. As much as it is okay to worry, you doctor is always there to allay your anxiety and explain what is happening. Fear of the unknown usually breeds stigma.
What are common side effects of chemotherapy?
Here are some of the more common side effects caused by chemotherapy. These are not listed in any particular order:
Can I take vitamins & supplements with chemotherapy?
It is important to mention all the drugs you may be taking for other reasons like blood pressure & diabetes tablets, vitamin supplements, herbal remedies etc. Some drugs may interact with the chemotherapy and it is important for your doctor to know so that necessary adjustments are made. These interactions may make side effects worse and affect how well chemo drugs work. General vitamins and mineral supplements are allowed especially if your feeding is poor. But remember to seek clearance frim you doctor.
Can I use medical marijuana during chemotherapy?
No. As much as it is purported to have benefits in symptom management, medical marijuana is NOT LEGAL in Kenya so my advice is NOT to use it.
Can I have SEX during chemotherapy?
Yes, you can but there are certain precautions that need to be taken. These vary with cancer type and type of chemo. Always consult your doctor before you engage in any type of sexual activity.
What are the danger signs to look out for during chemotherapy?
Call you doctor/nurse or right away if you have any of the following symptoms during chemo treatment:
