What You Need to Know About Chemotherapy
Chemotherapy, often referred to as "chemo," is a form of cancer treatment that utilizes powerful drugs to destroy cancer cells1. Its common goal is to shrink tumors, alleviate symptoms, and potentially cure cancer4. Often, chemotherapy is used in combination with other treatments, like surgery, radiation therapy, or immunotherapy, depending on your unique diagnosis and cancer stage2.
It's essential to understand that cancer and its treatments are unique to each individual. Together with your healthcare team, you will develop a tailored chemotherapy plan suited for your specific situation3. As you proceed, know that you are not alone in this journeyâ€”there are multiple resources and support systems available to help you both emotionally and physically.
Types of Chemotherapy
There are over 100 different chemotherapy drugs currently available1, and they are commonly grouped into categories based on how they work and their chemical structure. Most often, a combination of drugs is prescribed to maximize the chances of eliminating cancer cells while minimizing side effects2.
Some categories of chemotherapy drugs include:
- Alkylating agents: These drugs work by damaging cancer cell DNA, preventing replication. Alkylating agents are effective in treating various types of cancer, such as leukemia, lymphoma, and breast, lung, and ovarian cancer. Examples include cyclophosphamide, ifosfamide, and cisplatin3.
- Antimetabolites: Antimetabolites interfere with the synthesis of DNA and RNA, thus hindering cell growth and division. This category of drugs is often used in treating leukemia, breast cancer, and lung cancer. Methotrexate, 5-fluorouracil (5-FU), and gemcitabine are some of the antimetabolites used in chemotherapy treatment4.
- Plant alkaloids: Derived from plants, these natural compounds target specific proteins and enzymes necessary for cell division. Plant alkaloids are commonly used in the treatment of leukemia, lymphoma, and testicular, breast, and lung cancer. Examples include vincristine, vinblastine, and paclitaxel5.
- Anthracyclines: These chemotherapy drugs work by disrupting the DNA replication process and blocking specific enzymes essential for cell division. They are used in the treatment of leukemia, Hodgkin's and non-Hodgkin's lymphoma, sarcoma, and breast cancer. Doxorubicin, daunorubicin, and epirubicin are all examples of anthracyclines4.
- Topoisomerase inhibitors: These drugs inhibit the enzyme topoisomerase, which is crucial for the unwinding of DNA strands during replication. Topoisomerase inhibitors are often used in the treatment of leukemia, lung cancer, ovarian cancer, and gastrointestinal cancer. Examples include etoposide, irinotecan, and topotecan3.
Your healthcare team will decide on the most appropriate chemotherapy drugs and combinations based on your unique diagnosis and treatment plan2. Keep in mind that everyone's cancer journey is different, and the drugs used for your treatment may differ from those used for others with a similar diagnosis1.
How it Works
Chemotherapy is designed to target rapidly dividing cells, like cancer cells, in the body. Once administered, the drugs circulate throughout the bloodstream and can reach cancer cells virtually anywhere within the body1. Chemotherapy drugs primarily target the DNA or RNA of cancer cells to prevent cell division and growth4. This process often comes with the risk of also affecting healthy cells that naturally divide quickly, such as those in the bone marrow, digestive system, and hair follicles, which can cause side effects1.
Chemotherapy treatments are typically given in "cycles," with periods of treatment followed by a rest period for the body to recover1. The frequency and duration of treatment cycles vary depending on the type of chemotherapy drugs used, the stage and type of cancer, the overall health of the patient, and the patient's response to the therapy2. Some cycles may last a few weeks, while others may take several months to complete3.
The goal of chemotherapy can be different for each patient, as it may aim to:
- Curative: In some cases, chemotherapy can be used to eliminate cancer cells entirely, leading to a long-term remission or permanent cure4.
- Control: Sometimes, the goal of treatment is to stop or slow the growth of cancer cells, keeping the disease under control and improving the patient's quality of life4.
- Palliative: When cancer is advanced and a cure is unlikely, chemotherapy can be used to provide relief from pain, discomfort, and other symptoms4.
Keep in mind that, depending on your individual circumstances, chemotherapy may be used on its own or combined with other forms of cancer treatment, such as surgery or radiation therapy5. Your healthcare team will discuss the best course of action with you and design a personalized treatment plan to help you reach your specific goals3.
Preparing for Treatment
As you prepare for chemotherapy, it is essential to follow your healthcare team's instructions and have a thorough understanding of the treatment plan1. This will help you and your loved ones feel empowered and more confident in coping with the chemotherapy process. Here are some steps to take as you get ready for treatment:
- Understanding your treatment plan: Make sure you comprehend your chemotherapy regimen, such as its type, frequency, schedule, and the expected duration of treatment1. Your healthcare team will provide you with this information and be your main source of knowledge and support throughout the process2.
- Preparing for side effects: While you may not experience all the potential side effects of chemotherapy, be aware of the common ones and discuss with your healthcare team how to manage them proactively3. This may include medications for nausea4, pain management, and possible preemptive measures to reduce the chance of infection5.
- Arranging for support: Reach out to your friends and family, and let them know when your treatment will begin. Having a support system will make it easier for you to cope with the emotional and physical challenges that may arise during chemotherapy. You may also want someone to accompany you to appointments and provide transportation if needed, as the medication may cause you to feel temporarily fatigued or weak.
- Diet and exercise: A healthy lifestyle can play a vital role in preparing your body for chemotherapy. Focus on consuming a balanced diet that provides the nutrients needed to bolster your immune system and general well-being2. Similarly, engaging in regular, moderate exercise, such as walking or swimming, can help increase your energy levels and resilience3. Be sure to consult your healthcare team for personalized diet and exercise recommendations based on your specific health condition5.
- Organizing your medications: Make a list of all the medications you are taking, including prescriptions, over-the-counter drugs, and dietary supplements. Share it with your healthcare team to ensure there are no potential interactions with your chemotherapy drugs4.
- Communicating with work or school: Inform your employer or educational institution about your treatment schedule and potential side effects. Discuss your needs regarding time off and accommodations, and have a plan in place, should you require flexibility during the treatment process.
Remember, preparations for chemotherapy will vary depending on the individual patient and treatment plan. Always consult with your healthcare team for specific guidance and support1.
Side Effects and Management
Chemotherapy can cause a range of side effects that vary depending on factors like the specific drug, dosage, and individual response to treatment1. Keep in mind that not everyone will experience the same side effects or their severity, and your healthcare team will help you manage and cope with them effectively. Here are some common side effects and ways to manage them:
- Fatigue: Feeling tired or weak is common during chemotherapy1. To manage fatigue, ensure you get adequate rest, maintain a balanced diet, and engage in light to moderate exercise as recommended by your healthcare team. Allow yourself to take breaks and ask for help when needed.
- Nausea and vomiting: Chemotherapy drugs can cause an upset stomach, but medications called antiemetics can be prescribed to prevent or reduce nausea and vomiting12. Keep yourself hydrated and eat smaller, more frequent meals instead of the usual three large ones. Experiment with different foods to find what best suits your appetite and avoid strong odors or spicy dishes3.
- Hair loss: Hair loss can be emotionally challenging, but it often grows back once treatment is complete4. To cope, you could consider wearing a wig, scarf, or hat, or simply embrace your temporary look. Remember to protect your scalp from sun exposure and to use gentle hair care products when your hair begins to grow back12.
- Infections: Chemotherapy can weaken your immune system, making you more susceptible to infections1. To minimize risk, maintain proper hygiene, avoid exposure to individuals with contagious illnesses, and promptly report any symptoms of infection to your healthcare team, such as fever or persistent sore throat.
- Low blood cell counts: Chemotherapy can sometimes lead to a decrease in red blood cells (anemia), white blood cells (neutropenia), or platelets (thrombocytopenia)1. Your healthcare team will monitor your blood cell counts and may recommend medications or other interventions to address these issues if necessary4.
- Changes in appetite and weight: Some patients may experience changes in their taste buds or appetite during treatment, which may lead to weight gain or loss1. Work with a dietitian or follow your healthcare team's guidance to maintain a balanced diet that addresses your nutritional needs and preferences2.
- Emotional changes: It is natural to experience a range of emotions, such as anxiety or sadness, during chemotherapy4. Make sure you communicate your feelings to your healthcare team, friends, and family, and consider joining support groups, counseling sessions, or practicing stress-reduction techniques such as yoga or meditation.
It is essential to report any unusual or severe side effects to your healthcare team, as they can provide appropriate interventions or adjustments to your treatment plan2. Remember, effective management of side effects is critical for enhancing your overall well-being and quality of life during chemotherapy.
Emotional Support and Coping

- Hobbies and interests: Engaging in relaxing and enjoyable activities, such as reading, writing, knitting, painting, or gardening, can provide a therapeutic outlet for self-expression and offer a distraction from the challenges of treatment.
- Physical activity: Maintaining a light to moderate exercise routine, as recommended by your healthcare team, can help alleviate fatigue, boost energy levels, and improve your overall well-being. Exercise may also help combat feelings of anxiety and depression by releasing endorphins, which promote happiness.
- Explore spirituality: For some individuals, exploring spiritual beliefs or engaging in spiritual practices like prayer, meditation, or attending religious services can strengthen emotional resilience and provide a sense of comfort during treatment.
It is essential to remember that everyone's experience with chemotherapy is unique, and what works for one person might not work for another. Be kind to yourself and focus on finding the emotional support and coping strategies that best suit your individual needs and preferences. Your healthcare team can help guide you in identifying resources and support avenues specific to your situation.
