Breast Cancer Screening, Treatment & Surgeons at SJMC, Malaysia

Breast cancer is a disease in which cells in the breast grow and divide in an uncontrolled manner, creating a mass of tissue called a tumour. Signs of breast cancer can include feeling a lump in your breast, experiencing a change in the size of your breast and seeing changes to the skin on your breasts.

There are different types of breast cancer. The type of breast cancer depends on which cells in the breast turn into cancer. Breast cancer can begin in different parts of the breast.

Cancer originates in the breast tissue. It happens when breast cells mutate and grow out of control, creating a tumour. Like other cancers, breast cancer can invade and grow into the tissue surrounding the breast. It can also travel to other parts of the body and form new tumours.

Risk Factors for Breast Cancer

Risk Factors for Breast Cancer

A woman is 100 times more likely than a man to contract breast cancer.

Your risk increases as you get older. Nearly 80 percent of women diagnosed with invasive breast cancer are 50 or older.

An increased risk of breast cancer may be inherited from either parent.

Family History
Having a family member such as a mother, sister or cousin with breast or ovarian cancer can increase your risk.

In Malaysia, breast cancer is most common among the Chinese, followed by the Indians and then, Malays.

Personal History
If you’ve had breast cancer in one breast, there is an increased risk of developing cancer in the other breast.

Stay Informed
Understanding your risk factors can help you make informed decisions about screening, diagnosis and treatment.

About Breast Cancer

The breast is made up of milk glands and supporting tissues like fat. The milk glands are connected to the nipple by ductal system. Cells lining the milk glands and ductal system can undergo changes leading to cancer. The reason this happens is not fully understood.

Tumour can be either benign or malignant. Benign tumours remain growing in one area and cannot spread. Malignant tumours are made up of cancer cells which can spread to other parts of the body through the blood stream or the lymphatic system.

Types Of Breast Cancer

In general, there are four types which include:

  1. ductal carcinoma in situ
  2. invasive ductal carcinoma
  3. inflammatory breast cancer
  4. metastatic breast cancer

Who Should Get Breast Check-Up?

It is recommended that women who are 50 to 74 years old and are at average risk for breast cancer get a health screening or mammogram every two years. Women who are 40 to 49 years old should talk to their doctor or other health care professional about when to start and how often to get a mammogram.

A woman's risk for breast cancer is higher if she has a mother, sister, or daughter or multiple family members on either her mother's or father's side of the family who has had breast or ovarian cancer.

Early Detection

Women are encouraged to be more aware of how their breasts normally look and feel, so that it becomes easier to spot any suspicious changes. Identifying a change early offers the best chance of effective treatment if a cancer is diagnosed.

Detecting Breast Cancer

Detecting Breast Cancer

Monthly Breast Self Examination

  1. Lie down and put your left arm under your head. Use your right hand to examine your left breast. With your 3 middle fingers flat, move gently in small circular motions over the entire breast, checking for any lump, hardknot, or thickening. Use different levels of pressure – light, medium, and firm – over each area of your breast. Check the whole breast, from your collarbone above your breast down to the ribs below your breast. Switch arms and repeat on the other breast.
  2. Look at your breasts while standing in front of a mirror with your hands on your hips. Look for lumps, new differences in size and shape, and swelling or dimpling of the skin.
  3. Raise one arm, then the other, so you can check under your arms for lumps.
  4. Squeeze the nipple of each breast gently between your thumb and index finger. Report any discharge or fluid to your healthcare provider right-away.

Breast Cancer Screening (Mammogram)

  • A mammogram is an x-ray of the breast which can detect changes in the breast and small deposits of calcium. A cluster of very tiny specks of calcium may be an early sign of cancer.
  • Most doctors recommend that women above 50 years of age have mammograms regularly, every 1 to 2 years.
  • Women above 40 years of age with family history of breast cancer should have mammograms regularly.
Be Screened
Regular mammograms can help detect changes at the earliest stage.

Screening & Testing

To help find the cause of any signs or symptoms, a doctor does a careful physical exam and asks about personal and family medical history.
In addition, the doctor may do one or more of the tests below:

  • Imaging
  • Mammography
  • Ultrasound

If an abnormality is found on any of the tests and malignancy is suspected of a cancer then fluid or tissue must be removed from the breast so that the doctor can make a diagnosis. The doctor may refer you for further evaluation to a surgeon or interventional radiologist who may perform a biopsy.

  • All tissue or fluid will be sent to the laboratory to be checked by a pathologist for cancer cells
  • The pathologist can tell what kind of cancer it is and whether it has invaded nearby tissues in the breast
  • Special lab tests of the tissue can help the doctor learn more about the cancer learn more about the cancer, such as hormone receptor tests, silver-enhanced in situ hybridization (SISH) test

Be Guided
Biopsy result will guide the next phase of care if necessary.

Making decision about breast cancer treatment

It is very important to have a skillful multidisciplinary team to treat breast cancer as there are numerous treatment options.

Subang Jaya Medical Centre brings together the most advanced resources to manage the treatment of patients with early or advanced breast cancer.

Our multidisciplinary team includes surgeons, clinical oncologists, pathologists and radiologists working together to create the most effective treatment plan.

Our doctors make sure that each patient thoroughly understands factors such as the stage of the tumour and the range of treatment options, as well as the potential side effects of each therapy.

Doctors will guide patients through the sometimes complicated choices posed by these factors

Breast Cancer Treatment Choices

Breast Cancer Surgery

Surgery is usually the first line of attack against breast cancer.

Decisions about surgery depend on many factors. You and your doctor will determine the kind of surgery that is most appropriate for you based on the stage of the cancer, the “personality” of the cancer, and what is acceptable to you in terms of your long-term peace of mind.

Be Informed
Breast reconstruction is the rebuilding of the breast after mastectomy and sometimes lumpectomy. Reconstruction can take place at the same time as cancer-removing surgery, or months to years later. Some women decide not to have reconstruction and opt for a prosthesis instead.


Chemotherapy treatment uses medicine to weaken and destroy cancer cells in the body, including cells at the original cancer site and any cancer cells that may have spread to another part of the body.

Chemotherapy, also known as “chemo”, is a systemic therapy, which means it affects the whole body by going through the bloodstream.
There are quite a few chemotherapy medicines. In many cases, a combination of two or more medicines will be used as chemotherapy treatment for breast cancer.

Be Enlightened
Your oncologist will spend time with you and explain the possible side effects of chemotherapy and ways to deal with its side effects.

Radiation Therapy

Radiation therapy or radiotherapy is a highly targeted, highly effective way to destroy cancer cells in the breast that may stick around after surgery. Radiation can reduce the risk of breast cancer recurrence from 30-35% to 5-10%. Despite what many people fear, radiation therapy is relatively easy to tolerate and its side effects are limited to the treated area.

Intraoperative Radiation Therapy (IORT)

IORT is a high dose of radiation that is given during a surgery, to the area where the cancer was removed. IORT does as little damage as possible to normal tissue around where the tumour used to be.

IORT is different from standard radiation therapy. Standard radiation therapy treats the whole breast. IORT treats only the tissue surrounding the breast tumour. Most of the time, if your cancer does come back, it comes back near the site of the first cancer. This is the tissue that will be treated with IORT.

Whether you have IORT or traditional radiation to the whole breast will depend on several factors, including your age, the size of the tumour, the type of cancer cells that make up the tumour and the size of your breast.

Latest Technology
The Cancer & Radiosurgery Centre is equipped with sophisticated and highly advanced radiotherapy and radiosurgery facilities.

Hormone Therapy

Some breast cancers grow with the influence of hormones. Patients with both Estrogen Receptor positive (ER+) and Progesterone Receptor positive (PR+) have the best chance of responding to hormone therapy. Hormone therapy in breast cancer is aimed at affecting estrogen, a hormone that is required for the cancer to grow. For some women with early breast cancer, anti-cancer hormone treatment may be used as an additional treatment to reduce the chances of breast cancer recurrence. Hormone therapy can cause some side effects. These are dependent on the type of drugs taken and can vary from patient to patient.

Targeted Therapy

Targeted therapy is a form of cancer treatment that involves the use of antibodies or small molecules that bind specific sites on cancer cells in order to prevent cell growth and division. The aim of the treatment is to reduce and hopefully eliminate existing cancer cells in the human body while minimising side effects on normal cells. An increasing number of targeted drugs are becoming available for treatment of breast cancer. An example of targeted therapy for breast cancer is Trastuzumab, also known as Herceptin.

Other drugs may be needed to better control the cancer, for example Biphosphonates. Biphosphonates can be given to patients who are at high risk of bone metastases.

Which Doctor or Specialist Checks for Breast Cancer?

Since all women do not experience the same symptoms of breast cancer, it is imperative to get checked by a primary care physician or gynaecologist, who will perform a physical examination to evaluate the breast lump or mass. During the clinical breast exam, the doctor may recommend a mammogram or an ultrasound.

Cancer of the breast is recognized more often by gynaecologists than by any other physician, so gynaecologists must be well trained in diagnostic procedures that are crucial in revealing the nature of breast nodules.

If you have a problem in your breast, such as lumps, or if an area of the breast looks abnormal on a screening mammogram, doctors may further suggest a diagnostic mammogram. This is a more detailed X-ray of the breast or breast magnetic resonance imaging (MRI), a kind of body scan that uses a magnet linked to a computer.

Surgeons or Oncologists: Who Treats Breast Cancer?

  1. A breast surgeon or surgical oncologist is a general surgeon with a specific interest in treating patients with breast disease. This doctor uses surgery to treat breast cancer.
  2. A radiation oncologist is a doctor who uses radiation to treat cancer.
  3. A medical oncologist is a doctor who uses chemotherapy, hormone therapy, immunotherapy, and other medicines to treat cancer.

Most women undergo surgery for breast cancer, and many receive additional treatment after surgery too, such as chemotherapy, hormone therapy or radiation. In some cases, chemotherapy might be administered first before surgery.

At SJMC, our breast surgeons specialise in the surgical care of breast diseases and conditions. Breast surgeons perform breast biopsy, lumpectomy, mastectomy, breast reconstruction, and other procedures to treat many breast conditions, including breast cancer in both men and women.

When you visit our breast specialists, they will dive deep into your disease concerns, medical, and family history. Then, typically, a breast examination ensues. The breast exam may or may not include an ultrasound of the breast at a certain point of time.

Combining a comprehensive understanding of breast diseases and extensive experience in diagnosing as well as carrying out breast cancer treatment procedures are valuable characteristics that our breast specialists and breast surgeons’ excellence are built upon in providing you with comprehensive treatment and care.
