What are the Side Effects of Chemotherapy?

Cancerous cells tend to grow rapidly and chemo drugs destroy fast-growing cells. Since these drugs pass all over the body they can affect normal and healthy cells. Harm to healthy cells results in adverse effects but side effects are not always as worse as you might expect. To treat cancer, doctors pursue to administer chemo at high levels but keeping side effects at a minimum. And they also attempt to avoid the use of multiple drugs that have similar side effects.

Chemotherapy is accompanied with side effects.

 

Now the question arises what are the chemotherapy side effects which lies in the mind of most of the people. To each person, side effects are different.

 

We have listed down all the side effects caused by chemotherapy.

 

1. Vomiting and Nausea

Vomiting and Nausea

Approximately, 70 percent of the patients suffer from vomiting and nausea. This is because of the fact that chemotherapy affects parts of the brain and stomach that detect toxic substances.

 

So, the body tries to get rid of toxins and hence vomiting and nausea is caused. To avoid vomiting and nausea, anti-vomiting/nausea medicines are prescribed. 

 

There are certain types of nausea and vomiting :

  • Acute nausea and vomiting: This generally lasts a few minutes to few hours after the chemotherapy treatment. It generally goes away within 24 hours.
  • Delayed nausea and vomiting:  This is caused generally after the 24 hours of the chemotherapy. This may last upto 5-7 days.
  • Anticipatory nausea and vomiting: Anticipatory nausea and vomiting is a result of the experience of the previous chemotherapy that led to nausea and vomiting. The brain anticipates that vomiting and nausea will happen again from its past experience. So before the chemotherapy is given, the person actually starts to experience nausea and vomiting.
  • Breakthrough nausea and vomiting: The nausea and vomiting occur even after the consumption of drugs that avoid nausea and vomiting. This is breakthrough nausea and vomiting .

 

2. Hair Loss

Hair Loss

Here’s the scary part:

 

Chemotherapy drugs are very strong medications which attack fast growing cells. These drugs also attack other fast growing cells in your body which also include the one present in the hair roots. Hence, chemotherapy causes hair loss.

 

Sometimes, you may lose hair from your eyebrows, eyelashes, armpits, etc. also. The hair loss is temporary, and a patient can grow back his/her hair within three to six months after the treatment ends.

 

Ways to manage:

 

Before hair loss:

 

Do:

  • You should cut your hair short.
  • While washing your hair use a mild shampoo such as a baby shampoo.

Don’t:

  • Hair straightener or curling iron
  • Hair clips
  • Hair dyes or hair sprays

After hair loss:

  • You need to protect your scalp.
  • Satin pillow can be used for sleeping as they are more comfortable in sleeping as compared to cotton.
  • You should stay warm as after you lose hair, you may feel cold.

 

3. Fatigue

Fatigue

Fatigue is one of the most common side effect seen in the patients. It affects approximately 70% to 80% of the patients. It is caused due to the direct effect of chemotherapy. It is also caused due to anaemia as chemotherapy destroys too many red blood cells.

 

Fatigue is worst for people who are old, who are going through advanced cancer stages and who are going through combination of treatments such as radiotherapy and biological therapy. Fatigue is also caused by :

  • Appetite changes
  • Infection
  • Lack of sleep
  • Lack of activities
  • Medicines

Ways to manage:

  • Sleep atleast 8 hours: You should sleep minimum for 8 hours. It will help you relax and you won’t be experiencing fatigue.
  • Be active: You should perform basic exercises as they ease the fatigue and also helps a person to sleep well.
  • Relax: Try to meditate, pray, do yoga to relax your body and make it stress free.
  • Avoid doing too much: If you are experiencing fatigue, then you will not have much energy to do all the things that you wish to do. So avoid too much of work and ask your friends or family for help.
  • Have proper diet: Have a proper balanced diet. Prefer small meals so that the food is properly digested. Have lots of fluid intake and keep your body hydrated.
  • Plan schedule of work: If you are working, then plan your work schedule properly. There will be days when you have large amount of work and there will be days when you barely have work. So plan in such a way that you are not over - burdened with work.

 

4. Anaemia or low red blood cells

Anaemia

The function of red blood cells is to carry oxygen in your body. Anaemia is a condition when you have few red blood cells to carry oxygen throughout the body. It is caused as chemotherapy can kill cells which make red blood cells in the bone marrow. Anaemia can make you feel dizzy, tired, faint or feeling of breathlessness.

 

Ways to manage:

  • You need to take atleast 8 hours of sleep each night.
  • Have a balanced diet that contains proteins, iron and calories.
  • You should minimize your activities.
  • If red blood cells count is too low then blood transfusion is done.

 

5. Bowel problems

Bowel problems

Diarrhea is one of the common side effects of chemotherapy. Chemotherapy can damage the cells which are present in the lining of the digestive tract and hence diarrhea is caused. Constipation is also caused at times due to the medicines. If a person is inactive and is not doing any physical work, then also constipation can be caused.

 

Ways to manage:

 

In case of constipation:

  • You should drink lots of fluids in a day.
  • You should be active. You can remain active by walking, riding or performing yoga. If you are not able to walk, then you can ask your doctor to suggest some bed exercises.

In case of diarrhea:

  • Instead of having large meals, eat 5-6 small meals in a day.
  • Avoid food that is high in fibre as they make diarrhea worse.
  • Intake food that is high in salts as your body can lose these salts during diarrhea.

Avoid:

  • Drinks that are extremely cold or hot.
  • Any type of alcohol.
  • Foods that have caffeine such as black tea, coffee, etc.
  • Fried foods like french fries, chips, etc.
  • Spicy food.

Fertility problems

Many patients lose interest in sex during chemotherapy. Chemotherapy can also reduce fertility in women and men. In case of woman, it means that you may not become pregnant as chemotherapy can damage the ovaries.

 

In case of man, it means that you may not be able to father a child as chemotherapy may damage your sperm cells. After the treatment ends, fertility returns back for some but not for everyone.

 

Also, getting pregnant during cancer must be avoided as chemotherapy drugs may cause congenital disabilities.

 

Ways to manage:

For Women:

  • If you want to have children in future, you can preserve your eggs and use it in future.
  • Keep in mind that you must never get pregnant during chemotherapy as chemotherapy can destroy the foetus. Use birth control pills to avoid such situation.

I am suffering from severe stomach pain due to colon cancer stage 4, any medicine for pain relief

Male | 53

This pain occurs because the tumor is pressing on your belly inside. To relieve it, the doctor can prescribe you stronger drugs than those sold in the drugstore. These medicines are designed to ease the pain and make you comfortable. Keep telling your doctor how you feel so that they can change the medication when necessary to control the pain effectively.

Keeley Mums cancer has spread too far and has been deemed too aggressive for surgery. It started off in the breast and has spread to her brain, throat, lungs, liver and now also into her lymph nodes... She has been referred to oncology, who will look at her case and decide whether she is a fit for chemotherapy, and once they meet her they will decide if she is strong enough to go through it. IF mum is able to have the chemo, she will either be given a course of tablets to take, I believe they are one tablet a week. Or she will be given chemo via an IV and will have to go to once every three weeks for a few hours. If mum decides not to have chemo she will be referred to palliative care

Female | 67

If breast cancer advances to the brain, throat, lungs, liver, and lymph nodes, it is advanced cancer. Breast Cancer naturally develops in the cells of the human breast. But when cancer cells are balooned in size, it is called breast tumor. Chemotherapy treatment is regarded as one of the most popular therapies for advanced Breast Cancer. Chemotherapy can be done as an outpatient procedure if your mom can physically handle the treatment..

I am a 24 year old girl presenting all classic symptoms of hogdkins lymphoma, but im not sure what is the next step

Female | 24

I know it is hard to have symptoms that seem like­ Hodgkin's lymphoma. This kind of cancer can make the lymph node­s swell up. It can make you fee­l very tired too. You might lose we­ight without trying. You might get sweaty at night. The be­st thing to do is see a doctor who treats cance­r. The doctor might need to do a te­st called a biopsy to know for sure if you have Hodgkin's lymphoma. The­ biopsy can help the doctor plan the right tre­atment for you.
