Preventative tests to detect cancer continue to save lives | Health | The Magazine



A report published in Cancer magazine, the American Cancer Society, details that mortality rates associated with breast cancer between 1989 and 2018 have fallen faster.

The research team examined mortality rates from breast cancer and other related data, collected by women in the United States. US, and determined 27,000 deaths were stopped in 2018 thanks to better detection and care.

So, The report argues that this significant reduction is mainly due to women having breast cancer screening (mammograms) on time. It is also due to improved access to improved therapy after diagnosis.

Dr Carlos Malatay, the Ocology Service of the Solca Oncology Mastology Service, specifies that mammography, breast ultrasound, biopsies and magnetic resonance are the main tests patients can have to detect this disease on time.

"During the year, 675 new cases of breast cancer were diagnosed in Solca Guayaquil, 50% of these patients were aged between 40 and 59 years," said the expert.

Examinations

  • Breast cancer is the untreated growth of malignant cells in the breast tissue, which usually appears as a lump, tumor, mass or nodule in the breast.

  • There are two special tests for early detection of this type of adaptations.

The mammography. A quick and simple test involving several x-rays of the breasts. It is performed in women of 40 years. This test has 85% sensitivity and 95 to 97% specificity to detect breast lesions.

Ultrasound (ultrasound) of breasts. Abnormal ultrasound lesions are identified in the breast tissue, which can be benign or malignant. Together with mammography, it has sensitivity and specificity greater than 90% (between 95 and 97%).

It should be noted that, despite its usefulness, the one of these studies is not a definitive diagnosis. Mammography and ultrasound are tests that allow changes in the normal breast structure to be identified, so you should approach the specialist with the results of these tests.

How is breast cancer diagnosed?

Biopsy The only way to diagnose the disease is by carrying out a biopsy. This test involves removing the whole or part of the mass or nodule with local anesthesia, this is sent to the pathology laboratory to analyze cell composition and determine is a benign defect or our cancer.

Solca also has studies of immunosuppresses and molecular biology, which can offer personal treatments.

Other analyzes

BRCA genetic test is a next generation sequencing test (NGS) setting mutations in BRCA1 and BRCA2 genes. "Having mutations in any of these two genes increases the risk of inherited breast cancer and ovarian cancer syndrome, as well as other related cancers," explains Dr.. Arturo Prat Almeida, radiologist at Fron Ecomédica Unit. .

The result is very effective in terms of the specific nature and sensitivity of 99.9%. It can analyze up to 49 genes associated with 17 types of inherited cancers. All genes considered in the panel allow for action to be taken and are included in international guidance for patient management.

Procedure

It is unobtrusive, it is done by blood test. "The most important thing is that we can now stop and act before the cancer develops," said Dr. Prat. This analysis can be done after 18 years. The most suitable patients are those with a history of cancer in their family nucleus, not only for breast cancer, but for other types such as pancreatic cancer, kidney cancer, colon cancer and so on. .
