If you find the thought of losing your hair very upsetting, your doctor may be able to suggest a treatment that is less likely to cause
hair loss
. Sometimes there is a choice of drugs you can have. Your doctor will want to give you the treatment that is most likely to work best in treating your cancer. But there may be other cancer drugs that work just as well. It is certainly worth discussing.
Sometimes, the amount of hair that falls out can be reduced by using something called a cold cap. While you are wearing the cold cap, it lowers the temperature of your scalp. This reduces the blood flow in the scalp. So the amount of drug reaching the hair follicles on your head is lowered too. As smaller amounts of the cancer drugs get to the hair follicles, the hair is less likely to die off and fall out.
Cold caps only block certain drugs and are not suitable for use in all types of cancer. You can't really have scalp cooling if there is too high a risk that cancer cells could be present in the scalp blood vessels. This is because the cells in the scalp blood vessels might survive the treatment. It isn’t advisable if you are having leukaemia or
lymphoma
treatment. You can’t wear a cold cap if you are having continuous chemotherapy through a pump either, because you would have to wear the cold cap all the time, 24 hours a day.
Unfortunately, even if you can have it, the cold cap may not work. You may still have
hair thinning
and some people still lose their hair completely. You can't tell whether it will work for you until you try it.
If you have scalp cooling, you will have to
spend
longer at the hospital having your treatment. You have to wear the cold cap for a while before you have your drugs. The cold cap will make you feel cold all over, so it can be more comfortable to wear a jumper or ask for a blanket. Hot drinks will help you feel warmer. You may find that the cold cap gives you a headache.
Some doctors are not happy about their patients using scalp cooling for any type of cancer. They worry about the risk of cancer cells being left in the scalp. In theory, there is a risk that this could happen. But there has been very little research into the risk of cancer coming back after scalp cooling. So there is not enough evidence to know for sure whether scalp cooling is completely safe for most types of cancer. Some patients are not keen on scalp cooling for this reason, but others choose it. If you are interested in trying this way of keeping your hair, ask your specialist nurse if it is suitable for you. You can discuss the possible risks with your specialist if you are worried.
