Incidence of breast cancer increases in younger women



Among the risk factors for breast cancer, age over 50 is considered the most important. However, in recent years, the medical literature has recorded an increase in the incidence of the disease in women under 35 years of age.

Incidence of breast cancer increases in younger women

According to the clinical oncologist and palliative care at HCL (Hospital do Câncer de Londrina), Heloisa Maria Freire Marconato, the numbers bring an increase of 2% to 4 to 5% of diagnoses of the disease in younger Brazilians. The explanation, according to her, involves some factors. The main ones would be genetic (mutations of the BRCA1 and BRC2 genes), hormonal profile such as, for example, reproductive and hormonal history, in addition to environmental and behavioral factors.

“Lifestyle is very important, that is, taking care of food, exercising, not drinking excessively and not smoking,” he says. According to her, in approximately 10% of younger women with breast cancer, the cause is related to hereditary genetic mutation.


The SBM (Brazilian Mastology Society) campaign this year addresses exactly the change in lifestyle. “Several studies reveal that overweight and obesity, in addition to the lack of physical activities on a daily basis, increase the risks for breast cancer and still provide a poor quality of life for those undergoing treatment. Our warning is that the sooner you change your lifestyle, the better it will be for health and, thus, prevent new cases of breast cancer from occurring ”, says the entity’s president, Vilmar Marques, on the official website.

Marconato comments that the frequency of aggressive tumors is higher among younger women because they are usually outside the screening group and due to the difficulty in reading and interpreting the results of mammographic exams due to the high breast density. “The challenge ends up being greater because these women are in the reproductive phase, forming a family and a professional career. The impact ends up being very big ”, he says.


The Inca (National Cancer Institute) estimates 66,280 new cases of breast cancer for each year of the 2020-2022 triennium. In Londrina, the HCL registered 2,392 visits to breast cancer patients in 2019 and of this total, 414 were new cases.

When diagnosed at an early stage, the possibility of less aggressive treatments with satisfactory results is greater. However, it is important to know that even with the proper treatment, 30% of cases can progress to metastatic disease. “We understand that medicine is a disease where you can’t get a cure, but you can live with it”, says the HCL doctor.


The October Pink movement started in 1990 with the so-called “Race for the Cure” in New York. The event aimed to raise funds for research carried out by the Susan G. Komen Breast Cancer Foundation. The main symbol of the movement – the pink bow – was worn by the race participants and to this day it continues to remind everyone about the campaign.

The Pink October in Londrina involves a series of actions. Among them, there is the intensification of preventive collections, breast evaluation and requests for exams such as ultrasounds and mammograms, throughout the month of October at UBS (Basic Health Units).

On the 29th, starting at 3 pm, a conversation circle on overcoming cancer is scheduled with the psychologist Adriane Hisnauer Cantone. The meeting will be held through the Google Meet platform, which can be accessed through the link
