10 Essentials Before Chemotherapy: From Mindset to Strategy
Free cancer support
When you step onto the path of chemotherapy, questions come like waves. But the clearest asker is often the one with the greatest control. This guide, based on common patient concerns and international clinical recommendations, outlines 10 essentials to understand before treatment—helping you face chemotherapy with preparation, steadiness, and confidence.
Ten required courses before chemotherapy
How does chemotherapy work?
Chemotherapy drugs—delivered by injection or orally—target fast-dividing cells, such as cancer cells, hair follicles, intestinal lining, and bone marrow. The goal is to stop cancer cells from multiplying or trigger their death, thereby shrinking tumors, supporting surgery, or controlling metastasis. But because it also affects healthy cells, side effects such as nausea, hair loss, and fatigue may occur.
How is chemotherapy administered? Do I need a central line?
Most chemotherapy is given intravenously. Patients may receive a central line device such as a Port-A or PICC line for safe infusion, preventing leakage that could damage skin or muscle. These devices are important safety supports during treatment.
Is chemotherapy painful?
The infusion itself is usually painless. However, if you feel burning or discomfort at the injection site, inform a nurse immediately, as this may signal leakage outside the vein that requires urgent attention.
What are the most common side effects, and how can they be managed?
Side effects vary by drug but may include:
- Nausea and vomiting
- Fatigue
- Diarrhea or constipation
- Mouth sores
- Low white blood cell counts
The American Cancer Society recommends discussing anti-nausea medication, hydration, nutrition, and supportive therapies with your care team to reduce impact.
Will I lose my hair?
Not always. Some drugs, like paclitaxel or doxorubicin, are strongly associated with hair loss, while others may only thin hair. Most cases are temporary, but rarely permanent thinning may occur. Options include cold caps (scalp cooling), wigs, or scarves, which provide psychological comfort.
How long do side effects last? Can they be controlled?
Most side effects occur within 1–7 days after treatment. Delayed reactions may appear with specific drugs. Modern anti-nausea medications (such as 5-HT₃ inhibitors and NK₁ blockers) significantly reduce vomiting. Persistent issues should be discussed with your medical team, who can adjust dosages or add supportive therapies.
Does chemotherapy affect memory and concentration?
Yes—“chemo brain” is a real phenomenon. Up to 70% of patients may experience short-term or longer-lasting cognitive issues such as forgetfulness or reduced focus. Strategies include cognitive training, task scheduling, and regular breaks. Seek medical support if it becomes disruptive.
Will chemotherapy affect fertility?
Some drugs impair sperm production or ovarian function. It’s essential to discuss fertility preservation—such as sperm banking or egg freezing—before starting treatment.
How long will my chemotherapy last?
Chemotherapy is delivered in cycles—often every 3–4 weeks. A full course may require 4–6 cycles for curative treatment, while advanced cases may need longer regimens. Treatment schedules vary and should be clarified with your oncologist.
Will chemotherapy affect my family or others around me?
Chemotherapy drugs are excreted in urine or stool, but the risk to others is minimal. Hand hygiene, hydration, and general cleanliness are sufficient. Avoid pregnancy during chemotherapy, and discuss family planning with your medical team.

- Prepare psychologically and practically with scarves, wigs, or head coverings.
- Focus on nutrition and hydration to counter fatigue and digestive issues.
- Monitor for chemo brain and seek support strategies if needed.
