Chemotherapy

Understanding your treatment, one step at a time.

What is Chemotherapy?

Chemotherapy — often called "chemo" — is a type of cancer treatment that uses powerful drugs to kill cancer cells or stop them from growing and dividing. Unlike surgery or radiation, which target a specific area, chemotherapy is a systemic treatment — it works throughout your entire body.

This makes chemotherapy especially useful for cancers that have spread (metastasized) beyond their original site, or as an added layer of protection after surgery to eliminate any remaining cancer cells that can't be seen.

Chemotherapy is often combined with other treatments like surgery, radiation, immunotherapy, or targeted therapy. Your oncologist will create a treatment plan that's specifically designed for your type and stage of cancer.

An important truth: Chemotherapy has come a long way. Modern drugs are more effective and much better tolerated than those from even 10-15 years ago. We now have excellent supportive medications to manage side effects. Most patients tolerate treatment better than they expected.

How is Chemotherapy Given?

Chemotherapy can be given in several ways depending on the type of cancer, the specific drugs being used, and your treatment plan:

  • Intravenous (IV) Infusion: The most common method. The drug is delivered directly into your bloodstream through a vein, either via a small needle in your hand or arm, or through a port or PICC line. Sessions can range from 30 minutes to several hours.
  • Oral Tablets or Capsules: Some chemotherapy drugs come as pills you can take at home. You'll follow a specific schedule and may need regular blood tests to monitor your response.
  • Injection: Given as a shot under the skin (subcutaneous) or into a muscle (intramuscular). This is less common but used for certain drugs.

Treatment happens in "cycles": A cycle includes treatment days followed by rest days. For example, you might receive chemo on Day 1 and Day 8, then rest until Day 21 — that's one cycle. The rest period allows your healthy cells to recover before the next round. Most patients undergo 4-8 cycles, depending on the treatment plan.

Where you receive treatment: Most IV chemotherapy is given in a day hospital or infusion center — you come in the morning and go home the same day. Some regimens may require a short hospital stay (1-3 days). Your oncologist will explain your specific schedule in advance.

Before Your Treatment Starts

Preparation helps you feel more in control and makes the treatment process smoother. Here's what typically happens before your first chemotherapy session:

  • Blood Tests: You'll have blood work done before every cycle to check that your blood counts, liver function, and kidney function are at safe levels for treatment. If counts are too low, your session may be postponed by a few days.
  • Dental Check-Up: It's recommended to visit your dentist before starting chemo, since some drugs can affect your mouth and gums. Getting any dental work done beforehand reduces the risk of infection during treatment.
  • Port or PICC Line: If you'll be receiving multiple cycles of IV chemo, your doctor may recommend a chemo port (a small device placed under the skin of your chest) or a PICC line (a thin tube inserted into a vein in your arm). These make IV access easier and protect your smaller veins from repeated needle sticks.
  • Eating Before Your Session: Have a light, comfortable meal before treatment. Avoid heavy, greasy, or very spicy food. Staying hydrated is important — drink plenty of water in the days before and after treatment.

What to bring to your session: A family member or friend for company, a water bottle, light snacks, a book or phone for entertainment, a light blanket (infusion rooms can be cool), and any prescribed medications. Wear comfortable, loose-fitting clothes with sleeves that can be easily rolled up.

What Happens During Treatment

Knowing what to expect can ease a lot of anxiety. Here's what a typical chemotherapy session looks like:

  • Check-In: You'll arrive at the infusion center or day hospital. A nurse will check your vitals (blood pressure, temperature, weight) and review your latest blood test results.
  • Pre-Medications: Before the chemotherapy drugs, you'll receive anti-nausea medications, sometimes steroids, and occasionally antihistamines. These "pre-meds" are given to prevent or reduce side effects.
  • The Infusion: The chemo drugs are then administered through your IV, port, or PICC line. Duration varies widely — some drugs take 30 minutes, others may take 3-4 hours. You can read, watch videos, nap, or chat during this time.
  • Monitoring: Nurses will check on you regularly during the infusion, watching for any immediate reactions. If you feel anything unusual — itching, shortness of breath, burning at the IV site — tell your nurse right away.
  • After the Session: Once the infusion is complete, you'll be monitored briefly and then can go home. Most people can ride in a car but should not drive themselves. You'll receive instructions about medications to take at home and symptoms to watch for.

You can bring a companion. Most infusion centers welcome a family member or friend to sit with you during treatment. Their company can make the time pass more quickly and provide emotional support.

Common Side Effects

Chemotherapy works by targeting fast-growing cells — including cancer cells. But some healthy cells also grow quickly (like hair follicles, cells lining your mouth and gut, and blood cells), so they can be temporarily affected too. Not everyone experiences all side effects, and severity varies from person to person.

  • Nausea and Vomiting: One of the most feared side effects, but modern anti-nausea drugs are very effective. Most patients find nausea much more manageable than expected. You'll receive preventive medications before and after each session.
  • Hair Loss: Not all chemotherapy causes hair loss — it depends on the specific drugs. When it does occur, hair loss is temporary. Hair typically begins to grow back 3-6 weeks after treatment ends, sometimes in a different texture or shade.
  • Fatigue: Feeling tired is very common during treatment. It's not the same as ordinary tiredness — rest may not fully relieve it. Gentle activity like short walks can actually help. Plan your schedule to allow rest on your "low" days.
  • Low Blood Counts: Chemo can temporarily lower your white blood cells (increasing infection risk), red blood cells (causing anemia), and platelets (affecting clotting). Your doctor monitors these closely with blood tests.
  • Mouth Sores: Some drugs can cause sores or sensitivity in your mouth. Good oral hygiene, soft foods, and prescribed mouthwashes can help prevent and manage this.
  • Appetite Changes: You may experience changes in taste, loss of appetite, or food aversions. Eating small, frequent meals and choosing bland, easy-to-digest foods can help.

The most important thing to remember: Side effects are temporary. They go away after treatment ends. And modern supportive care has made chemotherapy much more tolerable than it was in the past. Don't let fear of side effects keep you from life-saving treatment.

Managing Side Effects: What You Can Do

You are not powerless against side effects. Here are practical steps to help you feel better during treatment:

  • Take anti-nausea medications as prescribed — don't wait until you feel sick. Prevention is much more effective than treatment. Take them on schedule, even if you feel fine.
  • Stay hydrated — drink 8-10 glasses of water daily. Add ginger tea or clear broths if plain water is unappealing. Avoid very cold or very hot drinks if you have mouth sensitivity.
  • Balance rest and activity — while rest is important, gentle exercise (a short walk, light stretching) can reduce fatigue and boost your mood. Listen to your body.
  • Eat smart — small, frequent meals are easier to tolerate than three large ones. Choose protein-rich foods (eggs, lentils, yogurt) to help your body recover. Avoid your favorite foods on chemo days — you don't want to associate them with nausea.

When to call your doctor immediately:

  • Fever above 100.4°F (38°C) — this could indicate an infection and is a medical emergency during chemo.
  • Uncontrolled vomiting that doesn't respond to medications for more than 24 hours.
  • Unusual bleeding or bruising — signs that your platelet count may be very low.
  • Difficulty breathing or chest pain — seek emergency care immediately.

Myths About Chemotherapy

Misinformation about chemotherapy causes unnecessary fear and sometimes leads patients to delay or refuse life-saving treatment. Let's address the most common myths:

Myth: "Chemotherapy is worse than the cancer itself."

FALSE. While chemotherapy has side effects, they are temporary and manageable. Untreated cancer progresses relentlessly. Modern chemo regimens are carefully balanced to maximize cancer-killing effect while minimizing harm to your body. Millions of people are alive today because of chemotherapy.

Myth: "You will definitely lose all your hair."

Not necessarily. Hair loss depends on the specific drugs used. Some chemotherapy regimens cause minimal or no hair loss. When it does occur, it is temporary — hair grows back after treatment ends. Scalp cooling caps can also reduce hair loss for some regimens.

Myth: "You can't work or live normally during chemotherapy."

Many patients do. While you'll need to adjust your schedule around treatment days and rest days, many people continue to work, care for their families, and maintain their social lives during chemotherapy. Your energy levels will fluctuate, but life doesn't stop.

Myth: "Chemotherapy burns you from the inside."

FALSE. Chemotherapy drugs are carefully formulated and dosed. They target fast-growing cells through specific biological mechanisms — they don't "burn" anything. If a drug leaks outside the vein (extravasation), it can cause local irritation, which is why nurses monitor your IV carefully.

Myth: "Natural remedies can replace chemotherapy."

No proven natural remedy can cure cancer. While complementary therapies (yoga, meditation, nutrition) can support your well-being during treatment, they should complement — not replace — evidence-based cancer treatment. Delaying proven treatment for unproven alternatives can cost lives.
