• Ana Rosa Quintana temporarily leaves Telecinco mornings due to breast cancer

The journalist

Ana Rosa Quintana

began her television program on Monday announcing that she suffers

from breast cancer

and will leave the space for "a season" to undergo "intense treatment."

"They have detected a carcinoma in my chest, fortunately it is localized and there are no metastases," said the presenter, 65 years old.


What is breast cancer?

Breast cancer is a tumor that begins in the breast tissue.

It occurs when the cells that are part of the breast change and proliferate uncontrollably.

There are different types of breast cancer depending on what type of cells the tumor originates from.

  • Ductal carcinoma

    : It begins in the cells of the breast ducts.

    It is the most common type

  • Lobular carcinoma

    : It begins in the lobules of the breast, the glands used for milk production.

  • Inflammatory breast cancer

    : In this type, cancer cells block the lymphatic vessels in the skin of the breast.

    The breast becomes warm, red, and swollen.

    It is a rare type of cancer.

  • Paget's disease of the breast

    : It is also rare.

    It affects the skin of the nipple and areola.

What is its frequency?

According to data from the Spanish Society of Medical Oncology (SEOM), it is estimated that 1 in 8 Spanish women will have breast cancer at some point in their life.

Although mortality from breast cancer has decreased in recent years thanks to screening programs and improved treatments, breast cancer continues to be the leading cause of cancer death in Spain in women.

In 2018, 6,534 women died of breast cancer in Spain.


What is the diagnosis of the illness?

The median relative survival of breast cancer after five years is 89.2% overall, according to data from SEOM.

The stage at which the cancer is diagnosed influences survival.

Survival in stage I is more than 98%, whereas in stages IV survival drops to 24%.


What are the symptoms?

A palpable nodule in the breast is the most frequent sign for which it is consulted, generally not painful, although retraction of the nipple or changes in the skin of the breast are also frequent.

Irritation, inflammation and the appearance of indentations are other signs that can indicate the presence of a tumor.

In addition, also the redness or peeling of the skin or the nipple as well as the discharge from the nipple should be reasons for consultation.

Which are the risk factors?

In addition to genetics, lifestyle and environment influence breast cancer risk.

For example, obesity and alcohol consumption significantly increase the chances of developing breast cancer.

The risk also increases with age, if menopause has begun at an advanced age or if they have not had children, among other factors.

It is estimated that 5-10% of breast cancers are hereditary.

20-25% of the mutations responsible for inherited breast cancers occur in the

BRCA 1 and 2 genes

.

How are breast tumors classified?

In addition to the origin of the tumor cells, tumors can also be classified by analyzing the genes for each tumor type.

This allows for a more accurate classification of breast cancer that is better correlated with the risk of disease relapse.

The molecular classification establishes four types of breast cancer:

Luminal A, Luminal B, HER 2 and basal like

.

Luminal tumors have positive hormone receptors, HER2 express HER2 and basal like or triple negative ones do not express hormone receptors or HER2.

The Luminal A subtype is the one with the best prognosis and the basal type is the one with the worst prognosis.
