Breast cancer is one of the most common cancerous diseases among the female population. Various factors contribute to the development of this disease, including genetics, unhealthy diet, poor lifestyle choices, elevated stress levels, environmental factors, as well as hormone changes.

Warning Signs of Breast Cancer

An early detection of breast cancer is crucial for getting a successful treatment. In order for the disease to be detected early, you should be aware of the warning signs of breast cancer.

One of the first symptoms is usually an appearance of a lump. However, this type of cancer is not always accompanied by a formation of a lump. There are some other symptoms which can appear in the early stages of this disease.

Here are some of the most commonly ignored breast cancer symptoms which require an immediate professional examination.

Unexplained Back Pain

Back pain is a sign which indicates that the breast tumors are forming. If you are dealing with breast cancer, you are likely to experience pain which is characterized by pressure on the ribs and spine.

Commonly, the pain occurs in the upper part of the back and feels like it’s coming from deep in the bones. If the pain is too intense, it can be a sign that the cancer has spread to the spine.


Fatigue is one of the breast cancer symptoms which are commonly experienced before the diagnosis. The fatigue which results from cancer cannot be reduced by rest or sleep.

It is usually very severe, and it is often accompanied by other symptoms, such as pain, depression, and sleep disturbance.

According to a number of researchers, this fatigue occurs because the tumor creates an imbalance of chemicals in the body.

Breast or Nipple Changes

Breast cancer can cause certain changes in your breast, such as an unexplained swelling or shrinking of the breast, an appearance of redness on the skin, or a development of dimples.

There may also appear some changes in your nipple. It can become sunken or inverted. The skin of your nipple can become dry, and it may start to peel, flake, or scale.

Also, there can be an appearance of a discharge from one of your nipples, which sometimes can be bloody.

Pain in the Armpit

According to several studies, the breast cancer starts to develop in the axillary lymph nodes. Swollen lymph nodes, tenderness or pain in the armpit may signal a presence of a tumor before it becomes noticeable in the breast.

In case you experience any discomfort in one of your armpits, you should compare it to the other one. If the difference is evident, you should immediately consult an expert.
