Don’t Give Up Even on Advanced Cancer – The Fourth Treatment Method: “Immunotherapy”

Immunotherapy has gained attention as the fourth treatment method for cancer, following surgery, chemotherapy (anticancer drug treatment), and radiation therapy.
Surgical treatment becomes difficult when the patient’s physical strength significantly declines, and chemotherapy and radiation therapy have drawbacks such as “side effects” and “less reliability compared to surgery.”
Immunotherapy does not require surgery and utilizes the patient’s own immune cells, causing almost no side effects. As the fourth treatment method, it is currently receiving widespread attention.
What is Immunotherapy?

■ Immunity is the body’s defense system that prevents external threats from harming it
Our body relies on immunity to eliminate external viruses and cancer cells that arise internally.
The key players in the immune system are white blood cells in the bloodstream. Among them, T cells (T lymphocytes) have the ability to attack cancer cells and play a crucial role in immunotherapy.
■ If we have immunity, why do we still get cancer?
In reality, even healthy individuals produce cancer cells every day.
Cancer cells arise due to genetic mutations and continue to proliferate uncontrollably.

It is said that approximately 5,000 cancer cells are generated in a healthy person’s body every day. Normally, these abnormal cells are quickly eliminated by the immune system, preventing them from developing into tumors.
However, some cancer cells are highly cunning. They retain normal cell markers or secrete proteins that suppress immune cell function, allowing them to evade immune detection and continue proliferating, eventually leading to cancer.
■ Immunotherapy that enhances immunity
The immune system weakens with age, and excessive stress, poor diet, and unhealthy lifestyle habits can promote cancer cell proliferation. Once cancer cells escape immune surveillance, they proliferate indefinitely.
Immunotherapy involves cultivating immune cells outside the body, further activating their immune capabilities, and reinfusing them into the body to restore the immune system’s ability to fight cancer.
Treatment Process
Blood Collection
20ml of blood is drawn from the patient (approx. 10 minutes).
Immune Cell Cultivation
Immune cells are cultivated and proliferated to about 1 to 2 billion cells (cultivation takes approximately two weeks).
Infusion
Outpatient infusion (approximately 1 hour).
Precautions & Side Effects
Treatment Eligibility
Since BAK immunotherapy requires culturing immune cells from the blood, it is available for all solid tumors except for blood cancers such as leukemia and malignant lymphoma. Additionally, treatment cannot be provided to patients who are positive for HIV, HTLV, or hepatitis B/C viruses.
Side Effects
Since the drug used for activation is removed before reinfusion, only the patient’s own immune cells are returned, resulting in minimal side effects. In some cases, a temporary fever up to 38°C may occur on the day of treatment but will subside within a few hours.
BAK immunotherapy is a private medical treatment and is fully self-funded (eligible for medical expense deduction).
Cancer Prevention & Recurrence Prevention
Building a Cancer-Resistant Body
BAK immunotherapy enhances immune cell quantity and quality, strengthening the body’s ability to fight cancer. A reinforced immune system helps eliminate newly emerging cancer cells, preventing cancer onset. This therapy is also effective in preventing cancer recurrence after chemotherapy or radiation therapy.
Building a Body Resistant to Cancer
As mentioned earlier, BAK immune cell therapy enhances the body’s ability to fight cancer by increasing both the quantity and quality of immune cells.
Additionally, strengthening the immune system helps the body naturally attack cancer cells that develop daily, achieving the goal of “building a body resistant to cancer.”
At the same time, this therapy is also effective in preventing cancer recurrence after chemotherapy and radiation therapy.
