International Standard Cancer Care

To many, cancer is seen as a single disease. The fact however is that 200 distinct types of cancer exist and each can be diagnosed at an early or late stage. What is required for effective cancer care is a collaborative multidisciplinary approach, wherein the Medical Oncologist, Radiation Oncologist and the Surgeons, collaborate together to decide on the best protocol for management of each case. At most times cancer patients require a treatment protocol that incorporates all these three areas. It is also very important that treatment is based on standardized clinical protocols and regimens. These protocols are developed using evidence gathered form treating thousands of cancer patients across the globe including South Asia.

At Asiri AOI we have launched a new generation Radiation Therapy Linear Accelerator, the most advanced in Sri Lanka and amongst a few in South Asia. Our tumour board consists of leading cancer specialists from the University of Pittsburgh Medical Centre, the only Cancer Centre in the country to offer this expertise.

Our team of Oncologists & Surgeons lead the field in terms of experience and qualifications. More importantly our nurses and paramedical technicians are dedicated to support every cancer patient and their family.

What is Cancer?

Cancer is a term used for diseases in which abnormal cells divide without control and invade other tissues. Cancer cells can spread throughout the body via the blood and lymph system. When cancer cells move from their point of origin and invade other parts of the body through the bloodstream and lymph system, the process is referred to as metastasis.

Cancer is not contagious and often occurs due to a mix of hereditary and environmental factors. More than 200 different types of cancer exist. Most cancers are named after the organ or type of cell in which they originate. For example, cancer that starts in the cervix is called cervical cancer, and cancer that starts in basal cells of the skin is referred to as basal cell carcinoma.

Origins of cancer

All cancers originate from cells, the body's basic units of life. The human body is composed of about 100 trillion cells. Cells keep the body healthy by growing, dividing, and producing new cells when the body needs them. Normally, when cells become old or damaged, they die and new cells replace them. However, this process may be disrupted when cells divide and replicate uncontrollably, even if new cells are not needed by the body. This unnecessary cell growth may be the result of mutated or damaged genetic material, known as DNA. When this type of cell growth occurs, the result is an unneeded increase in the overall quantity of cells in the body. This increase in new cells can form a mass of tissue called a tumor. However, not all tumors are cancerous.

Tumors can be grouped into two categories


These tumors are not cancerous and are rarely life-threatening. Often, they can be removed. After removal, regrowth of the tumors are not common. Additionally, these cells do not spread to other parts of the body.


These tumors are cancerous. Malignant cells can attack nearby healthy tissues. These cells also have the ability to metastasize or spread to other parts of the body.

Some cancers do not form tumors. Leukemia, a cancer of the marrow and blood, is a common example of such a cancer.

Cancer types can be grouped into broader categories

The main categories of cancer include:


Cancers that originate in the skin or in tissues that line or cover internal organs.


Cancers that originate in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.


Cancer that originates in blood forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced, and enter the blood.

Lymphoma and Myeloma

Cancers that originate in the cells of the immune system.

Central Nervous System Cancers

Cancers that originate in the tissues of the brain and spinal cord.

Discovery 600 PET/CT

Asiri AOI offers four dimensional (‘4D’) PET/CT, which combines the power of two imaging technologies and helps physicians account for variations in tumor size, shape and location when patients move or breathe. With it, doctors see the most complete and accurate images possible of a patient’s tumor and surrounding body structures. They use this information to ensure radiation treatment impacts only the tumor and not healthy tissue around it. Asiri AOI is the only center in Sri Lanka to have this powerful imaging modality.

A positron emission tomography (PET) scan is an imaging test that shows the metabolic activity (energy usage) of your body. A PET scan can give your doctor information about how your brain is working. It may be used to detect cancer, seizures, or Alzheimer's. In patients with memory disorders, doctors use PET scans of the brain to look for brain tumours that can be surgically removed.

Doctors often use the PET Scan diagnostic exam to detect cancer and measure the effects of cancer treatment. PET is very useful in detecting the activity of cancer, because malignant cells grow at a fast rate, they metabolize more sugar than normal cells. This can give your doctor a glimpse into how aggressive a tumour is or how its growth is slowed by therapy.

  • MRI
  • What is it?

    An MRI (Magnetic Resonance Imaging) scan uses a large magnet, radio waves, and a computer to create a detailed, cross-sectional image of internal organs and structures in your body.

    Your doctor can use this test to diagnose you or to see how well you've responded to treatment. An MRI scan differs from CT scans and X-rays, as it does not use potentially harmful ionizing radiation.

    What is MRI used for?

    MRI scanners are particularly well suited to image the non-bony parts or soft tissues of the body. They differ from computed tomography (CT), in that they do not use the potentially damaging ionizing radiation of X-rays. The brain, spinal cord and nerves, as well as muscles, ligaments, and tendons are seen much more clearly with MRI than with regular X-rays and CT; for this reason, MRI is often used to image knee and shoulder injuries.

    In the brain, MRI can differentiate between white matter and grey matter and can also be used to diagnose aneurysms and tumours. Because MRI does not use x-rays or other radiation, it is preferred when frequent imaging is required for diagnosis or therapy, especially in the brain. However, MRI is more expensive than X-ray imaging or CT scanning.

  • CT Scans
  • What Is a CT Scan?

    A computerized tomography scan (CT or CAT scan) uses computers and rotating X-ray machines to create cross-sectional images of your organs, bones, and other tissues. Like one piece in a loaf of bread, this two-dimensional (2D) scan shows a “slice” of the inside of your body. It shows more detail than a regular X-ray, allowing doctors to detect conditions like cancer.

    They can help locate a tumour, blood clot or infection, and can guide treatment plans and procedures like biopsies, surgeries and radiation therapy.

    Doctors can compare CT scans over a period of time to assess the effectiveness of ongoing treatments.

  • Digital X-Ray
  • Digital radiography / X-ray is a form of X-ray imaging, where digital sensors are used instead of traditional photographic film. This makes it much quicker and easier to digitally transfer and enhance images. Also, while traditional X-rays are considered safe, digital X-rays produce 80% less radiation. This means the patient receives much less radiation exposure with digital X-rays.

  • Mammography
  • A mammogram is an X-ray examination of the breast. It is used to detect and diagnose breast disease in women who either have breast problems, such as a lump, pain, or nipple discharge, as well as for women who have no breast complaints. It can be used to check for breast cancer in women who have no signs or symptoms of the disease.

    The procedure allows detection of breast cancers, benign tumours, and cysts before they can be detected by palpation (touch).

  • Ultra sound scan (Sonogram)
  • An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. Ultrasound scans are safe because they use sound waves or echoes to make an image. Ultrasound is safe, non-invasive, and does not use ionizing radiation.

    Ultrasound scans are used during pregnancy to evaluate fetal development, and they can also detect problems in the liver, heart, kidney, or abdomen. They may also assist in performing certain types of biopsy.


Medical Oncology

Focuses on treatment of cancer with chemotherapy, targeted therapy, immunotherapy, and hormonal therapy.

Surgical Oncology

Surgical oncology uses surgery to diagnose, stage and treat cancer. Surgical oncologists may also perform palliative surgeries to help control pain, increase a patient’s comfort level and manage cancer-related symptoms and side effects.

Whether a patient is a candidate for surgery depends on factors such as the type, size, location, grade and stage of the tumor, as well as issues related to the patient’s health, including age, physical fitness and other medical conditions.

Many patients may have cancer surgery combined with other treatments, such as chemotherapy, radiation therapy and/or hormone therapy. Nonsurgical treatments may be administered before or after surgery to help prevent cancer growth, metastasis or recurrence.

Radiation Oncology

Focuses on treatment of cancer with radiation.

What is Radiation Oncology?

Medical technology has improved tremendously in recent years, especially in the field of radiation oncology. Recent advancements in radiation therapy have revolutionized the treatment of cancer, leading to better clinical outcomes for patients. A specialty physician called a radiation oncologist manages and oversees each patient's radiation treatment. If you have been diagnosed with cancer, you may have the option of receiving radiation therapy as part of your cancer treatment. Your doctor will help determine if radiation therapy is right for you.

What is Radiation Therapy?

Radiation therapy, sometimes referred to as “radiotherapy,” is a type of cancer treatment that uses high-energy ionizing radiation to shrink tumors and kill cancer cells. It is a local treatment, meaning that it targets only the tumor, while sparing surrounding healthy tissue.

There are two ways radiation can be administered to patients:

  1. External beam radiation
  2. External beam radiation therapy delivers radiation through the use of a large machine called a linear accelerator that precisely aims radiation beams from outside of the body at the cancerous tumor.

  3. Brachytherapy or internal radiation therapy
  4. Brachytherapy is a type of radiation therapy in which radioactive particles known as seeds are placed within the body on the tumor or nearby the cancer cells.

*About half of all cancer patients receive some type of radiation therapy at some point during the course of their cancer care.

Radiation Therapy: A Walk-Through

There are six basic steps to radiation therapy that give patients an idea of what to expect.

Consultation is the first step of the radiation therapy process. This involves an appointment with an oncologist, who reviews a patient’s medical records, pathology reports and radiology images and performs a physical examination. If, based on this review, treatment by radiation therapy is chosen, the patient will be offered an appointment for simulation.

Palliative Care

At Asiri we firmly believe in providing the best palliative care to patients who are in need, through a multidisciplinary team of professionals, whose primary responsibility is to:

  • Ensure that the environment is homely and comfortable, while having sophisticated medical facilities at hand, rather than the typical hospital atmosphere.
  • Provide relief from pain and other symptoms that distress the patient.
  • Affirm life, and to regard dying as a normal process.
  • Neither hasten or postpone death.
  • Integrate the psychological and spiritual aspects of patient care.
  • Offer a support system to help the patient live as actively as possible until death.
  • Help the family to cope with the patient’s illness and their own bereavement, including bereavement counselling if necessary.
  • Enhance the quality of life, and maybe also positively influence the course of the illness.
