Breast Cancer Symptoms

Let’s start learning all the symptoms of breast cancer!


Daniel Gonzalez M.D. - Breast Lump

Except in case of very aggressive tumors that can be detected for the first time outside the breast, breast cancer is detected most often in the breast itself.

If breast cancer is confined to the breast, it can appear in several forms. Here are the most common situations: (you can watch the video starting in the part of the symptoms of breast cancer when the tumor is still only in te breast, simply clicking on this video)

Situation 1: Breast Cancer is located in the middle part of the gland

Most often the tumor is in the middle of the breast, in its glandular area. The woman usually feel it when showering or having a bath.

And if she’s following an early detection program of breast cancer, usually she discovers it before it causes symptoms.

Being located most of the breast tissue in the upper outer quadrant of the breast, is in this area that most often breast cancer appears.

Situation 2: Breast Cancer is located near the nipple

When located near the nipple, breast cancer can produce two different symptoms.

The first symptom is a nipple deformity. The tumor may make the nipple twist and change its form, and therefore appears asymmetric with respect to the other breast’s nipple.

The tumor can also pull the nipple inward the breast, causing its invagination.

In both situations nipples of both breasts are asymmetrical.

The second symptom is the appearance of a bloody discharge from the nipple.

When there is blood coming from the nipple not always has to be a breast cancer. Anyway, it is very important to consult a doctor as soon as possible.

Situation 3: Breast Cancer is located close to the skin

When the tumor is located very close to the skin, as it progressively grows, it can produce two different symptoms.

The first one appears when the tumor reaches the skin, breaking it and producing an ulcer that doesn’t heal. That is associated with bad odor, because the ulcer usually gets infected with normal skin bacteria.

The second symptom happens without breaking the skin. The tumor compresses the lymphatic drainage that goes below the skin, which make fluid accumulate. The “orange peel” appears with a bunch of little holes in the skin, caused by the cellulite beneath.

Both symptoms usually announce that the tumor has already achieved a big size.

Situation 4: Breast Cancer grows deep and reaches the pectoral muscle

When the tumor grows inward it can infiltrate the pectoral muscle, which is deep in the breast, fixing the breast to this muscle. To observe this fact the woman has to lean forward, dangling breasts.

The breast where the tumor is infiltrating the pectoral muscle, will be moving less, and woman can note the asymmetry regarding the unaffected breast who hangs freely, unattached.

We have seen symptoms due to breast cancer in the breast itself.

But what happens when the tumor escapes from the breast, either through the lymph system or through the blood?

Let’s see it!


(If you want to watch the breast cancer symptoms video starting on the symptoms of the tumor who has escaped the breast, you can clic just below)

When the tumor is already out of the breast it may be because it has followed two different paths: the lymphatic system or blood.

Let’s see where each path leads!

Situation 1: Breast Cancer has escaped the breast through the lymphatic vessels

Daniel Gonzalez M.D. - Breast Axillary Nodes

When breast cancer chooses lymph vessels to travel to other parts of the body, it can follow two paths.

The first one, the most common, is to go to the axilla.

There are many axillary nodes that can collect tumor cells. These cells accumulate there and make the size of the axillary nodes get bigger. Eventually they will become palpable.

If many tumor cells accumulate in the armpit and affect many lymph nodes, they can disrupt the collection of lymphatic fluid from the arm, which will gradually start to swell, although this is very rare.

The second path, the least frequent, is to go to the internal mammary chain, which is located in the thoracic cavity, just below the breastbone.

Although cancer cells accumulate in these nodes, as they are situated inside the chest, we have no clinical way to detect these enlarged nodes. The only way of discovering them is by performing a scanner.

A less frequent travel site of tumor cells through the lymphatic vessels is the supraclavicular area.

We could feel a lump in the hole situated above the first rib in the lower neck, and if it’s large enough it could compress the brachial plexus nerves, causing strange sensations in the arm, loss of sensation in the fingers, or even cramping or feeling a throbbing pain. Nevertheless, this is rare.

Situation 2: Breast Cancer has escaped through the blood vessels

Daniel Gonzalez M.D. - Breast Cancer Metastases

When breast cancer cells reaches blood, breaking a nearby blood vessel, tumor cells travel throughout the body and can get to places where, due to their special conditions, they like to live.

In case of breast cancer, the most common sites where metastases appear are:

Most frequent #BreastCancer metastasis: bones, lungs, brain and liver Click To Tweet


When tumor cells grow in the bone and metastasis are very big, they can break the layer that covers bone. This layer, the periosteum has great pain sensitivity. When it breaks pain appears.

This cancer growth compromises bone strength, and especially if bone has to bear weight, it could break.

An special case of bone metastases occurs when vertebrae are affected. It can cause back pain, as is the case of Martha we mentioned earlier.

When vertebrae breaks, it can cause neurological symptoms known as spinal cord compression syndrome.


When tumor cells get to the lungs, they usually create separate cell groups. Some time later, multiple metastases will appear.

If they cancel enough lung function, shortness of breath (a symptom called “dyspnea“) appears.

If they touch a breathing tube (bronchus), they irritate it, causing a very troublesome dry cough.

If placed near a blood vessel, they may break it, pouring a little blood with that cough.

The Brain:

When groups of tumor cells get to live within the brain, metastases appear, increasingly large. As they push neighboring neurons, these neurons begin to operate in an altered way.

Therefore two types of symptoms may occur:

  • irritative” symptoms, in which pushed neurons fire uncontrolled flashes: the woman can have seizures;
  • or “deficit” symptoms, in which the neurons stop functioning and their work is left undone. We can have loss of mobility, loss of vision, loss of sensibility, and so on.

In both cases, if there is much tumor in his head, because the skull is a closed cavity with a single large outlet as there is not enough room for as many cells (including neurons and tumor cells), we start having headaches, gradually growing up in intensity and frequency.

The Liver:

When breast cancer cells get to the liver, they begin to grow wildly and begin to crush liver cells.

If the liver cells break, their contents, transaminases, will access the blood, thus increasing their blood levels (we can detect that in a blood test).

If they compress small bile conduct inside the liver, bile may accumulate and the patient’s skin gets a yellow tint (phenomenon called jaundice).

As you can see, breast cancer can be the cause of many signs and symptoms.

Let’s summarize them!


This is the summary, on video, of all the symptoms breast cancer can cause. You are just a clic away of seeing them!

In the Breast itself

Most often we find the tumor in an early diagnostic test, or it is palpated when woman performs self-examination of her breasts or finds it in the shower.

Less often a bloody discharge from the nipple, ulceration of the skin, “orange peel”, or breast fixation to the pectoral muscle can occur.

In regions of lymphatic drainage

The most common way of discovering breast cancer is finding a lump in the armpit.

Less often a swelling of the arm, a lump in the neck, neurological symptoms in the arm can appear, or we can find enlarged internal mammary lymph nodes in a thoracic scanner.

Anywhere else in the body

The most common symptoms are bone pain or fractures if bone is involved; cough, hemoptysis or dyspnea if metastases are located in the lungs; increased transaminases or jaundice if the liver is affected; or neurological symptoms if the cancer goes to the brain.

Knowing the symptoms of breast cancer is very important.

Do not forget to carry out any early diagnosis measures of this cancer that your doctor prescribes.
