Hair loss (alopecia) can be a side effect of certain chemotherapy drugs.
Hair loss usually begins 2 to 3 weeks after chemotherapy treatment starts. The amount of hair you lose depends on the chemotherapy you receive. The good news is that your hair will grow back. Hair usually starts to grow back 1 to 2 months after chemotherapy ends.
It can be difficult to prepare yourself for the loss of your hair. It’s OK to allow yourself to grieve the loss of your hair. Encourage family members, especially children, to express their thoughts and feelings about your hair loss. Remember, losing your hair does not change who you are as a person.
Tips for dealing with hair loss:
- Get a short haircut before you begin treatment. It may help make your adjustment to hair loss easier.
- Shop for a wig before your hair is gone, especially if you wish to match your natural color. Some insurance companies cover the cost of a wig.
- Be gentle with your hair. Use mild shampoos and soft hair brushes. Avoid chemicals including permanent waves, bleach, peroxide or hair dye.
- Remember to cover your head or use sunscreen (with an SPF of at least 15) on your scalp.
- Shaving your head before your hair starts to fall out can give you a sense of control.
- Try other head coverings
- Accessorize your makeup or jewelry
Hot flashes are caused by hormonal changes that interfere with your body’s ability to lower its temperature.
Chemotherapy can cause sudden menopause that can bring on hot flashes. Hormonal (anti estrogen) treatment of breast cancer can also cause hot flashes.
Men who are being treated with hormonal therapy for prostate cancer can also experience hot flashes.
Tips For Dealing With Hot Flashes:
- Dress in layers of cotton clothing.
- Keep your home or workplace at a cool temperature.
- Keep ice water or cool beverages available.
- Take a cool shower.
- Try deep-breathing exercises.
- Talk with your doctor about vitamins and/or medications that may help decrease and/or control these symptoms
How soon you will feel better depends on many things, including your general health and the kinds of chemotherapy you have been taking.
Some side effects go away fairly quickly and others may take months or years to disappear completely. Sometimes side effects can last a lifetime.
Platelets are cells in your blood that stop bleeding by plugging damaged blood vessels and helping the blood to clot. People with low levels of platelets bleed more easily and are prone to bruising.
Certain types of chemotherapy drugs can damage the bone marrow so that it does not make enough platelets. Thrombocytopenia caused by chemotherapy is usually temporary.
Call your doctor or nurse immediately if you notice any of the following:
- Easy, heavy, or prolonged bleeding
- New, pinpoint, red, flat spots anywhere on your body
- Persistent nose bleeds
- Blood in vomit
- Bloody or black stools
- Increased bruising of skin
- Unusually heavy menstrual bleeding
- Headaches
Tips for dealing with low platelet count:
- Do not take aspirin, aspirin-containing products or ibuprofen unless approved by your doctor.
- Do not use rectal or vaginal suppositories.
- Use stool softeners to prevent straining with bowel movements.
- Avoid activities, such as sports, that can cause you to fall or develop bumps or bruises.
- Do not have sexual intercourse.
- Use a soft-bristle toothbrush.
- Use an electric razor instead of a blade razor.
Anemia is a decrease in the number of red blood cells and amount of hemoglobin, a protein that helps your blood carry oxygen. Anemia results in your blood being unable to carry oxygen throughout your body. Cancer-related anemia can be caused by chemotherapy, radiation therapy, iron deficiency, bleeding, the cancer itself or a combination of these or other things.
Anemia makes you feel tired. If you are anemic, you may also have the following symptoms:
- Difficulty thinking
- Dizziness and weakness
- Shortness of breath with mild activity

- Felt confused or cannot think clearly
Tips for dealing with anemia
- Eat small, balanced meals every 2 to 3 hours. The best sources of iron are beef and other meats. Additional sources of iron include beans, lentils, iron-fortified cereals and dark green, leafy vegetables. Foods containing vitamin C, such as citrus fruits, help increase iron absorption.
- Stay as active as you can. At least 10 to 30 minutes daily of light exercise can ease tiredness.
- Take short naps, but do not let them interfere with your nighttime sleep.
- Take your time getting up from a lying or sitting position. Getting up too fast can make you dizzy and cause you to fall.
Chemotherapy may lower your infection-fighting white blood cells (neutrophils) – a condition known as neutropenia.
When your blood counts are low, you may be at higher risk of getting an infection.
Your doctor can tell if you have neutropenia by ordering a complete blood count (CBC). Your risk depends on:
- How low your white blood count falls
- How long your white blood count is low

- loss of balance
- clumsiness
- difficulty picking up objects
- walking problems
- jaw pain
- hearing loss
- stomach pain
- constipation
Peripheral neuropathy can range from mild to severe and may occur during treatment or after all of your treatment has been completed.

- Call your doctor or nurse if you have new pain or pain that is not controlled by your pain medication within 24 hours
- Take your pain medication as prescribed.
- Do not let the fear of addiction cause you to not take your pain medication as prescribed
Cancer treatment can cause physical, hormonal and emotional changes that affect your sexual drive and raise issues of fertility. Don't let your treatment related fatigue, surgical pain or other side effects take away from nurturing your relationship with your partner.
There are many ways to handle the potential reproductive issues you may have at this time.
Dealing with sexuality and reproductive issues
- Bring your partner with you to doctor or nurse appointments.
- Talk openly with your doctor or nurse about your concerns.
- Talk with your partner about your hopes, concerns, fears and needs.
- Practice birth control during treatment.
- Discuss sperm banking, egg retrieval or embryo freezing with your doctor before starting treatment.
