New Delhi, Oct 7, 2017: Breast Cancer is one of the supreme causes of female deaths, however, it’s awareness is low in India. A leading Radiologist, Dr. Jyoti Arora, Associate Director, Medanta – the Medicity states that 8 out of 10 cases of breast lumps are not cancerous and undergoing biopsy is the only way to rule out breast cancer.

In India, two responses with respect to breast lumps are generally normal. Either the feeling of a lump formation in the breast is disregarded or the patient gets hysterical. The two responses are extreme and caused by the absence of proper awareness but in altogether different ways.

A recent study summarized that its predominance is as high as 25.8 per 1,00,000 women and its death rate are 12.7 per 1,00,000 women, mentioned ANI.

Dr. Arora has disclosed that because of the absence of awareness, a huge number of Indian women do not choose  appropriate tests and treatment.

Arora said, “One of the first symptoms of breast cancer is the formation of lumps in the breast. While many women from not so educated and aware sections of society do not identify lump in the breast as a reason enough to see the doctor, those who are aware of the connection between breast lumps and cancer does not realize that in 8 out of 10 cases, lumps in breasts are non-cancerous. For them, a breast lump is the synonym of breast cancer and they feel it’s the end of their life so do not get it evaluated.”

As the lumps are associated with pain, some females do not seek medical advice. The non-cancerous lumps are cyst formation, fibro-adenoma which is an abnormal non-cancerous growth, or maybe a temporary sign due to woman’s menstrual cycle.

Cancerous lumps are usually hard to feel and not associated with pain.

So if a female feels a lump, she should visit a breast specialist who will get a mammography and ultrasound done. If a solid lump is confirmed on imaging then in most of the cases biopsy would be needed to confirm whether the lump is cancerous or not.

To check cancerous cells, a radiologist removes tissue while conducting a breast biopsy from the suspected area for lab testing.

“There are various types of biopsies that a patient is offered. Tru cut needle biopsy is performed in majority of the cases, however when the abnormality is very small, subtle or when seen only on the mammograms in the form of calcifications or only on the breast MRI, vacuum-assisted breast biopsies (VABB) are preferred as they increase the accuracy and sensitivity of getting a representative sample from the abnormal area. Through VABB, more tissue can be removed than by the true cut needle biopsy and hence a more accurate report can be generated by the pathologist,” added Arora.

One should look for changes in the breast in terms of size and shape. Other than formation of lump, observe whether there are skin changes such as swelling and redness, in drawing of the nipples or if there is pain, irritation, change of color, or peeling and flaking of nipple skin.

  • Long-term night shift work among women increased the risk of cancer by 19%.
  • A meta-analysis using using international data from 61 articles comprising 114,628 cancer cases and 3,909,152 participants.
  • These studies found an association between long-term night shift work and risk of 11 types of cancer.

Women who work overnight have a comparatively high risk of developing cancer than women who do not, say researchers. An analysis of international data has confirmed an association between night-shifts and cancer.

“Our study indicates that night shift work serves as a risk factor for common cancers in women,” said Xuelei Ma, co-author of the study from West China Medical Center of Sichuan University in Chengdu, China.

  • Long-term night shift work among women increased the risk of cancer by 19 percent.
  • Nurses (working in night shifts) had the highest risk of breast cancer, of all the occupations analysed.
  • The population of women working on night shifts have an increase risk of skin (41%), breast (32%) and gastrointestinal cancer (18%).
  • Among female nurses alone, those who worked the night shift had an increased risk of breast (58%), gastrointestinal (35%) and lung cancer (28%).

Methodology

  • A meta-analysis using data from 61 articles comprising 114,628 cancer cases and 3,909,152 participants from North Amercia, Europe, Australia and Asia.
  • The articles consisted of 26 cohort studies, 24 case-control studies and 11 nested case-control studies.
  • These studies found an association between long-term night shift work and risk of 11 types of cancer.

“Nurses that worked the night shift were of a medical background and may have been more likely to undergo screening examinations,” the researcher suggested.

“Long-term night shift workers should have regular physical examinations and cancer screenings,” Ma noted.
