Hearing that someone needs chemotherapy can bring a mix of emotions and countless questions and anxiety on “how is it actually going to feel like?” The truth is that every chemotherapy journey is different. It depends on the type of cancer, the medications being used, overall health, and how the body responds to treatment. While no two experiences are exactly alike, understanding some of the common physical and emotional changes can help in feeling more prepared for the road ahead.
How does Chemotherapy work and how is it administered?
Cancer cells grow and divide uncontrollably and Chemotherapy or ‘Chemo’ uses powerful medicines to destroy cancer cells or stop them from multiplying. Most chemotherapy is administered through an intravenous (IV) infusion, however it can also be provided through tablets, capsules, injections or topical creams. The treatment usually takes place in cycles. The patient receives treatment and then gets a recovery period before the next session. A treatment cycle can take anywhere from a few minutes to a few hours. Some people need a continuous infusion, which can last several days
Effects and Side Effects of Chemotherapy
Chemotherapy drugs target all fast-growing cells, including cancer cells. This means chemotherapy drugs destroy cancer cells but can also damage other cells in your body, potentially causing side effects. Blood cells and the cells in your skin, hair follicles and digestive tract are examples of cells that grow and multiply quickly. That’s why some common side effects of chemotherapy occur in these areas, including:
Fatigue : One of the most common experiences during chemotherapy is fatigue.. Many patients describe feeling physically and mentally drained, even after completing simple tasks such as taking a shower, preparing a meal, or going for a short walk. Learning to listen to your body becomes especially important during treatment. Rest when you need to, accept help when it is offered, and remember that conserving energy is part of taking care of yourself.
Changes in Appetite and Digestion : Chemotherapy affects the digestive system and makes meals seem bland, metallic, or unappealing. Some people experience nausea, while others struggle with constipation, diarrhoea, or loss of appetite. Eating can sometimes feel more like a task than a pleasure. Eating smaller meals throughout the day, staying hydrated, and choosing foods that feel comfortable can make a significant difference.
Hair Loss and Changes in Appearance : Hair loss is one of the most visible and emotional side effects of chemotherapy. , including eyebrows and eyelashes often begins to thin or fall out a few weeks after treatment starts. Hair loss can feel like a constant reminder of the cancer journey. The encouraging news is that hair usually grows back after treatment ends. Planning ahead with scarves, hats, wigs or scalp-cooling options can help individuals feel more prepared and maintain a sense of control during treatment.
Tingling, Numbness, and Nerve Changes : Some chemotherapy medications can affect the nerves in the hands and feet, causing a condition known as ‘peripheral neuropathy’. Patients may experience tingling sensations similar to pins and needles, numbness in the fingers or toes, burning or shooting pain, difficulty buttoning clothes or picking up small objects, increased sensitivity to hot and cold temperatures, or problems with balance and walking. These symptoms can sometimes develop gradually, making them easy to overlook at first. Reporting them early to your healthcare team is important to prevent them from becoming more severe.
Oral Health and Dental Challenges : Many patients are surprised to learn that Chemotherapy can also indirectly affect dental health. The tissues inside the mouth renew themselves very quickly, making them particularly sensitive to treatment. You may experience painful mouth sores, swollen or tender gums, bleeding while brushing or flossing, dry mouth caused by reduced saliva production, increased sensitivity to spicy, salty, or acidic foods, and a greater risk of oral infections. A dental check-up is often recommended before starting treatment,
Over-the-counter drugs and vitamins can interfere with chemotherapy : Although vitamins are a safe way to improve health, taking high doses of vitamins, especially A, C, and E, can backfire during chemo. Some studies show they interfere with the way some drugs work. It is important to talk to your doctor about which vitamins and any other over-the-counter drugs and supplements you usually take can be used during treatment.
Increased Risk of Infection : Chemotherapy can temporarily reduce white blood cell counts, making it harder for your body to fight infections. This means that something as simple as a minor cold can require closer attention than usual. You may be advised to wash your hands more frequently, avoid contact with people who are ill, monitor your temperature regularly, and contact your healthcare team immediately if you develop a fever.
The importance of Support and Hope.
Chemotherapy is not a journey to be faced alone. Having a trusted friend, family member, or caregiver as your ‘Cancer Buddy’ by your side can make an enormous difference. It can provide practical help, emotional support, transportation to appointments, and an extra set of ears during medical discussions. On difficult days, simply having someone who listens without judgment can be incredibly valuable.
Cancer treatment can make one lose their sense of normalcy and feel like life now only revolves around appointments, medications, and side effects. That is why it is advised to continue activities that they enjoy, such as reading, gardening, walking, watching a favourite show, spending time with loved ones, or enjoying a quiet cup of coffee. These familiar moments can provide stability and reassurance.
Chemotherapy is often one of the most challenging experiences a person will face. There may be moments of frustration, exhaustion, and uncertainty. Yet many people discover strengths they never knew they possessed and find support from family, friends, caregivers, and healthcare professionals along the way. While chemotherapy may temporarily change many aspects of daily life, it does not define who you are. You are still the same person with the same hopes, goals, and dreams and every cycle completed is a step toward recovery and healing.
