Understanding Side Effects of Breast Cancer Chemotherapy

Side Effects of Chemotherapy for Breast Cancer Explained

Starting chemotherapy for breast cancer brings many questions and concerns. What does it feel like? How will it affect your body? Will you be able to continue daily activities? These are all normal thoughts as you prepare for treatment.

Every person's experience with chemo is a bit different. The side effects you face depend on your specific treatment plan, medications, and your body's response. However, when you know what might happen, you can prepare yourself better and feel less anxious as you start your treatment.

Why side effects occur during breast cancer chemotherapy?

Chemotherapy works by targeting fast-growing cells in your body, which is why it's effective against cancer cells that multiply quickly. However, your body has many healthy cells that also grow quickly, such as those in your digestive tract, hair follicles, and bone marrow.

When chemotherapy travels through your bloodstream, it can't separate cancer cells from healthy cells. As a result, it ends up harming these healthy cells, which leads to certain complications in your body.

However, these side effects typically improve once your breast cancer treatment ends. Most begin to fade within weeks after your final session, though some may last for a few months. Your body has its own healing abilities and works constantly to repair affected healthy cells.

When you know what are the side effects of chemotherapy for breast cancer, it helps you understand what's coming and how to deal with it better.

7 short-term side effects to know before starting with chemotherapy

Short-term side effects of breast cancer chemotherapy treatment usually start during the chemo and go away once it ends. These include:

  Nausea, vomiting, and diarrhoea

But don't worry, as your doctor will prescribe medications for the side effects of breast cancer chemotherapy treatment. In addition, eating small, frequent meals and staying well-hydrated will also help.
• •

  Hair loss or thinning
