MIC is a chemotherapy treatment used to treat lung cancer.
This information should ideally be read with our general information about chemotherapy and your type of cancer.
MIC is named after the initials of the chemotherapy drugs used. These are:
You will have MIC in the chemotherapy day unit or during a short stay in hospital. A chemotherapy nurse will give it to you. During treatment, you will usually see a cancer doctor, a chemotherapy nurse or a specialist nurse. This is who we mean when we mention doctor or nurse in this information.
Before or on the day of treatment, a nurse or person trained to take blood (phlebotomist) will take a blood sample from you. This is to check that it is okay for you to have chemotherapy.
You will also see a doctor or nurse before you have chemotherapy. They will ask you about how you have been. If your blood results are alright on the day of your treatment, the pharmacist will prepare your chemotherapy. Your nurse will tell you when your treatment is likely to be ready.
Your nurse will give you anti-sickness drugs as an injection into a vein or as tablets. Your treatment will be given through one of the following:
a short thin tube (cannula) that the nurse puts into a vein in your arm or hand.
a fine tube that goes under the skin of your chest and into a vein close by (central line).
a fine tube that is put into a vein in your arm and goes up into a vein in your chest (PICC line).
Your nurse will give you:
mitomycin (a purple fluid), which is usually given as a drip (infusion). It can also be given as a slow injection into an infusion of salt water (saline).
ifosfamide (a colourless fluid), which is given as a drip.
cisplatin (a colourless fluid), which is also given as a drip.
Your nurse will usually run the drip through a pump, which gives you the treatment over a set time. You’ll have extra fluids through your drip before and after the cisplatin. This is to protect your kidneys. Although the mitomycin is often given first, the drugs may be given in a different order. This doesn’t change how well they work.
Your course of MIC
You will have chemotherapy as a course of several sessions (or cycles) of treatment over a few months. Each cycle of MIC takes 21 days (three weeks).
On the first day, you will have mitomycin, ifosfamide and cisplatin. After this, you will have a rest period for the next three weeks.
At the end of this rest period, you will start your second cycle of MIC. This is exactly the same as the first cycle. MIC chemotherapy can be given in different ways. You can ask your nurse or doctor to explain how you will have your treatment and the number of cycles you are likely to have.
Before you go home, your nurse or pharmacist will give you anti-sickness drugs to take. They may also give you anti-diarrhoea tablets if you need them. Take all your tablets exactly as the nurse or pharmacist has explained to you.
Possible side effects of MIC
Back to top
We explain the most common side effects of MIC here. But we don’t include all the rare ones that are unlikely to affect you.
You may get some of the side effects we mention, but you are very unlikely to get all of them. Always tell your doctor or nurse about the side effects you have. Your doctor can prescribe drugs to help control some of these. It is very important to take the drugs exactly as your nurse or pharmacist has explained. This means they will be more likely to work better for you. Your nurse will give you advice about managing your side effects. After your treatment is over, the side effects will start to improve.
Contact the hospital
Your nurse will give you telephone numbers for the hospital. You can call them if you feel unwell or need advice any time of day or night. Save these numbers in your phone or keep them somewhere safe.
When the chemotherapy is being given
Some people might have side effects while they are having the chemotherapy.
Rarely, cisplatin may cause an allergic reaction while it’s being given. Your nurse will check you for this. If you have a reaction, they will treat it quickly. Signs of a reaction can include: a rash; feeling itchy, flushed or short of breath; swelling of your face or lips; feeling dizzy; having pain in your tummy, back or chest; or feeling unwell. Tell your nurse straight away if you have any of these symptoms.
The drug leaks outside the vein
If this happens when you’re having mitomycin, it can damage the tissue around the vein. This is called extravasation. Tell the nurse straight away if you have any stinging, pain, redness or swelling around the vein. Extravasation is not common, but if it happens it’s important that it’s dealt with quickly.
If you get any of these symptoms after you get home, contact the doctor or nurse straight away on the number they gave you.
Pain along the vein
If you have this, tell your nurse straight away. They will check your drip site and slow the drip to ease the pain.
Other possible side effects of MIC
Back to top
Risk of infection
MIC can reduce the number of white blood cells in your blood. This will make you more likely to get an infection. When the number of white blood cells is low, it’s called neutropenia.
Contact the hospital straight away on the contact number you’ve been given if:
your temperature goes over 37.5°C (99.5°F) or over 38°C (100.4°F), depending on the advice given by your chemotherapy team
you suddenly feel unwell, even with a normal temperature
you have symptoms of an infection – this can include feeling shaky, a sore throat, a cough, diarrhoea or needing to pass urine a lot.
The number of white blood cells usually increases steadily and returns to normal before your next treatment. You will have a blood test before having more chemotherapy. If your white blood cells are still low, your doctor may delay your treatment for a short time.
Bruising and bleeding
MIC can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot. Tell your doctor if you have any bruising or bleeding you can’t explain. This includes nosebleeds, bleeding gums, blood spots or rashes on the skin. Some people may need a drip to give them extra platelets.
Anaemia (low number of red blood cells)
MIC can reduce the number of red blood cells in your blood. These cells carry oxygen around the body. If the number of red blood cells is low, you may be tired and breathless. Tell your doctor or nurse if you feel like this. If you are very anaemic, you may need a drip to give you extra red blood cells (blood transfusion).
Loss of appetite
You may lose your appetite during your treatment. Try to eat small meals regularly. Don’t worry if you don’t eat much for a day or two. If your appetite doesn’t improve after a few days, let your nurse or dietitian know. They can give you advice on getting more calories and protein in your diet. They may give you food supplements or meal replacement drinks to try. Your doctor can prescribe some of these and you can buy them from chemists.
This may happen in the first few days after chemotherapy. Your doctor will prescribe anti-sickness (anti-emetic) drugs to help prevent or control sickness. They may also give you a steroid drug to help. Take the drugs exactly as your nurse or pharmacist explained to you. It’s easier to prevent sickness than to treat it after it has started.
If you still feel sick, or vomit twice or more in 24 hours, contact the hospital on the numbers they gave you as soon as possible. They will give you advice and may change the anti-sickness drug to one that works better for you. Some people may need to go to hospital for a short time so the doctors and nurses can control their sickness.
Some anti-sickness drugs can make you constipated. Tell your doctor or nurse if this is a problem.
Feeling very tired is a common side effect. It’s often worse towards the end of treatment and for some weeks after it’s finished. Try to pace yourself and get as much rest as you need. It helps to balance this with some gentle exercise, such as short walks. If you feel sleepy, don’t drive or operate machinery.
You will usually lose all the hair on your head when having MIC chemotherapy. Your eyelashes, eyebrows and other body hair may also thin or fall out. This usually starts after your first or second cycle of chemotherapy. It is almost always temporary and your hair will grow back after chemotherapy ends. It is important to cover your head to protect your scalp when you are out in the sun until your hair grows back. Your nurse can give you advice about coping with hair loss.
Your mouth may become sore and you may get ulcers. This can make you more likely to get an infection in your mouth. Gently clean your teeth and/or dentures morning and night and after meals. Use a soft-bristled or children’s toothbrush. Your nurse might ask you to rinse your mouth regularly or use mouthwashes. It’s important to follow any advice you are given and to drink plenty of fluids.
Tell your nurse or doctor if you have any problems with your mouth. They can prescribe medicines to prevent or treat mouth infections and reduce any soreness.
You may get a bitter or metallic taste in your mouth or find that food tastes different. This should go away when your treatment finishes. Try using herbs and spices (unless you have a sore mouth or ulcers) or strong-flavoured sauces to give your food more flavour. Sucking boiled sweets can sometimes help get rid of a bitter or metallic taste. Your nurse can give you more advice.
Changes in the way the kidneys work
Cisplatin can affect how your kidneys work. You will have blood tests before and during treatment to check this. You’ll have extra fluids through a drip before and after chemotherapy. This is to protect your kidneys. If necessary, you may be given medicine to help you to pass urine.
Your nurse will ask you to drink plenty of fluid. Tell them if there are any changes in how much urine you are producing.
Less common side effects of MIC
Back to top
Ifosfamide may irritate your bladder and cause discomfort when you pass urine. Drink plenty of fluids - at least two litres (three and a half pints) during the 24 hours following chemotherapy. It is also important to empty your bladder regularly and to try to pass urine as soon as you feel the need to go.
Contact the hospital straight away if you feel any discomfort or stinging when you pass urine, or if you notice any blood in it.
Numb or tingling hands or feet
These symptoms are caused by the effect of cisplatin on nerves. It’s called peripheral neuropathy. You may also find it hard to fasten buttons or do other fiddly tasks.
Tell your doctor if you have these symptoms. They sometimes need to lower the dose of the drug. The symptoms usually improve slowly after treatment finishes but in some people they may never go away. Talk to your doctor if you are worried about this.
Changes in hearing
MIC may cause ringing in the ears (tinnitus) and you may lose the ability to hear some high-pitched sounds. Hearing loss can be more severe with higher doses and longer courses of treatment. Very occasionally, your sense of balance may be affected. If you have any hearing loss or balance changes, they may be permanent. However, tinnitus usually improves when treatment ends. Tell your doctor if you notice any loss of hearing or tinnitus.
Changes to the lungs
Mitomycin can cause changes to the lungs. Always tell your doctor if you develop wheezing, a cough, fever or feel breathless. You should also let them know if any existing breathing problems get worse. If necessary, they can arrange for you to have tests to check your lungs.
Extreme drowsiness, loss of balance, hallucination and confusion
These side effects are rare. If you notice any of these effects, it's important to tell your doctor straight away.
It’s important to let your doctor know straight away if you feel unwell or have any severe side effects, even if they’re not mentioned above.
Other information about MIC

Blood clot risk
Cancer increases the chance of a blood clot (thrombosis) and chemotherapy can add to this. A clot can cause symptoms such as pain, redness and swelling in a leg, breathlessness and chest pain. Contact your doctor straight away if you have any of these symptoms. A blood clot is serious but your doctor can treat it with drugs that thin the blood. Your doctor or nurse can give you more information.
Some medicines can interact with chemotherapy or be harmful when you are having chemotherapy. This includes medicines you can buy in a shop or chemist. Tell your doctor about any medicines you are taking, including over-the-counter drugs, complementary therapies and herbal drugs.
MIC may affect your fertility (being able to get pregnant or father a child). If you are worried about this, you can talk to your doctor or nurse before treatment starts.
Your doctor will advise you not to become pregnant or to father a child during treatment. This is because the drugs may harm a developing baby. It’s important to use effective contraception during and for a few months after chemotherapy. You can talk to your doctor or nurse about this.
If you have sex within the first couple of days of having chemotherapy, you need to use a condom. This is to protect your partner in case there is any chemotherapy in semen or vaginal fluid.
Changes to your periods
Chemotherapy can sometimes stop the ovaries working. You may not get a period every month and they may eventually stop. In some women, this is temporary, but for others it is permanent and they start the menopause.
Women are advised not to breastfeed during treatment and for a few months after. This is in case there is chemotherapy in their breast milk.
Medical and dental treatment
If you need to go into hospital for any reason other than cancer, always tell the doctors and nurses that you are having chemotherapy. Give them contact details for your cancer doctor.
Talk to your cancer doctor or nurse if you think you need dental treatment. Always tell your dentist you are having chemotherapy.
