Chemotherapy, also referred to as ‘chemo,’ is one of the common and effective treatments used to treat cancer. These treatments involve powerful medications that are specifically designed to destroy rapidly growing cancer cells and prevent them from spreading. Being suggested to get chemotherapy for your cancer treatment can be a daunting experience.  

If you are concerned about how it works, what to expect during the treatment, and how to manage the side effects of the treatments, then read further; this blog is for you! Let’s get into this!

What is chemotherapy and how does it work?

Chemotherapy uses specific anti-cancer drugs that are designed to target and kill fast-growing cells in the body, which also includes both cancer and healthy cells. Cancer cells grow more quickly than most healthy and normal cells; chemotherapy is especially effective in destroying rapidly growing cells.

One of the disadvantages of chemotherapy drugs is that they can’t distinguish perfectly between cancer cells and other fast-growing healthy cells, such as those in hair follicles, mouth cells, and bone marrow, which is why many side effects appear in cancer patients.

Chemotherapy used for different treatment purposes

Here’s how chemotherapy used as treatment purposes, including:

  • Curative purpose: To completely eliminate cancer in patients.
  • Adjuvant therapy: To destroy any remaining cancer cells after surgery or radiation in patients. 
  • Neoadjuvant therapy: These are chemotherapy treatments, used to shrink a tumor before surgery.
  • Palliative care: To relieve symptoms and improve the quality of life in advanced-stage cancer patients.

The chemotherapy process : Step by step

Here’s how a healthcare provider decides the chemotherapy treatment in a patients, starts from:

Consultation and Assessment

Before starting the chemotherapy, your oncologist might suggest different tests, including blood tests, imaging and sometimes biopsy, to determine the best type and dosage of chemotherapy drugs often suited to your health condition.

Treatment planning

Your doctor decides the treatment plan, which includes:

  • The type of chemotherapy drugs
  • Dosage and frequency
  • Number of treatment cycles

Chemotherapy might be given alone or combined with other cancer treatments such as radiation therapy and targeted therapy.

Administration of chemotherapy

A certified healthcare provider delivers chemotherapy to cancer patients. Here’s how Chemotherapy can be delivered in different ways, including:

  • Intravenous (IV): These types of chemotherapy drugs are given through a vein. 
  • Oral : (Pills or capsules)
  • Injection: Some of these chemo drugs are given into a muscle or under the skin
  • Topical application: These are specific creams applied to the skin for certain types of cancers. 

Treatments are usually given in cycles, which is a period of treatment followed by proper rest and a healthy diet, which allows the body to recover before the next round.

Monitoring and Follow-up: During the chemotherapy, many doctors closely monitor the blood counts, organ function, and overall progress. Practicing regular check-ups will help to ensure the treatment is responding well and side effects are managed immediately.

Common side effects of chemotherapy

Chemotherapy is a powerful cancer treatment, but it can also affect healthy cells, which often leads to temporary side effects. While the intensity of these side effects can vary depending on the type of the chemo drug and patients overall health conditions.

Here are some of the common side effects of chemotherapy, including:

  • Fatigue
  • Nausea and vomiting
  • Hair loss
  • Mouth sores
  • Loss of appetite
  • Anemia
  • Low white blood cells
  • Changes in skin and nail
  • Mood changes or brain fog

Many side effects of chemotherapy are temporary and will get better soon after the patient completes their treatments. Currently, modern oncology medicine has developed many other medications to help control nausea, pain, and other side effects.

Recovery Tips for Managing Chemotherapy Side effects
