Increase in breast cancer mortality in Campinas worries and Health reinforces the importance of mammography | Campinas and Region

The increase in breast cancer mortality worries health authorities in Campinas (SP). The 4th edition of the Bulletin of the Population-Based Cancer Registry of Campinas, released this Tuesday (4), shows that the total number of deaths from the disease, which had suffered a drastic drop at the turn of the 2010s, presents an upward curve, reaching the fee of 17.8 deaths per 100,000 women in the triennium 2019-2021 – see chart below.

The effect caused by the Covid-19 pandemic, with the decrease in demand for tests for early diagnosis, such as mammography, is the likely cause of the increase.

“We still don’t have total evidence, but it is a fact that the demand for exams has decreased a lot in the pandemic years, both because of the message of stay at home itself, and because of the difficulty of supply, since all health services were focused on urgency and emergency. There was clearly a drop. What worries us is how these behavioral changes can reflect in this period without seeking tests”, analyzes Andrea von Zuben, director of the Department of Health Surveillance (Devisa).

The third leading cause of death among women in Campinas, breast cancer continues to be the neoplasm with the highest incidence in the city, being responsible for 30.6% of cases – in the previous bulletin, the rate was 29.6%.

“In the period from 2010 to 2017, around 530 new cases of invasive breast cancer were diagnosed per year. The calculation of the incidence rate by the female population shows us that 71.3 women per 100,000 inhabitants per year are diagnosed with this neoplasm“, points out the study.

  • 530 new cases of breast cancer diagnosed per year (on average)
  • 71.3 of every 100 thousand women of the city has the diagnosis of the disease per year
  • Of all cases of cancer in residents of Campinas, 30.6% are breast
  • The death rate reached 17.8 deaths per 100,000 women in the triennium 2019-21

Andrea von Zuben reinforces the message for women to act in prevention and seek health services, as there are mammography exams available in the city. The cure depends on the moment of diagnosis and the aggressiveness, but it can reach 95% of early detection cases.

“It is important that women return to prevent themselves. There is mammography available, there is also a pap smear, which helps to detect cervical cancer, the second leading cause.

The bulletin released this Tuesday shows that during the study, analyzing data from patients between 2010 and 2017, an average of 65 cases of breast cancer were detected per year in which the neoplasm was not in its invasive stage, being called carcinoma in situ.

“At this stage the cancer cells are located within the breast ducts, not yet compromising the surrounding breast tissue”, explains the document.

However, among all the cases diagnosed in the city in the period, 31% of them already had metastasis“which indicates a more complex treatment and a worse prognosis and survival”, warns the bulletin.

According to the National Cancer Institute (Inca), of the Ministry of Health, breast cancer is a disease caused by the disordered multiplication of breast cells, which multiply forming a tumor.

“There are several types of breast cancer. Therefore, the disease can evolve in different ways. Some types have rapid development, while others grow more slowly. These different behaviors are due to the characteristic of each tumor”, informs the Inca.

According to Health, breast cancer has several causes, which can be environmental or hereditary. The most important risk factor is age, being rare before the age of 35.

“In the period from 2010 to 2017, the median age of diagnosed cases was 58 years, with the minimum age of diagnosis being 21 years and the maximum of 103 years”, highlights the report.

The treatment is offered in the public health network.
