How Breast Cancer Spreads To The Lungs
Breast cancer starts in the breast. As the abnormal cells divide and multiply, they form a tumor. As the tumor grows, cancer cells can break away from the primary tumor and travel to distant organs or invade nearby tissue.
Cancer cells can enter the bloodstream or migrate to nearby lymph nodes under the arm or near the collarbone. Once in the blood or lymph systems, cancer cells can travel through your body and land in distant organs or tissue.
Once cancer cells reach the lungs, they can start to form one or more new tumors. Its possible for breast cancer to spread to multiple locations at the same time.
Recurrence Of Metastatic Breast Cancer
Metastatic breast cancer is considered a chronic disease, so it doesnt go away and recur.
But in recent years, people under age 50 have seen a particularly strong decline in death rates due to breast cancer, according to the Centers for Disease Control and Prevention .
These declines are due in part to improved screening and treatment for the disease.
There are a few general facts that are helpful to know about breast cancer outlook:
- Breast cancer is the most common cancer diagnosis in the United States, according to the
When Do People Get A Metastatic Breast Cancer Diagnosis
Metastatic breast cancer can occur at different points:
- De novo metastatic breast cancer: About 6% of women and 9% of men have metastatic breast cancer when theyre first diagnosed with breast cancer.
- Distant recurrence: Most commonly, metastatic breast cancer is diagnosed after the original breast cancer treatment. A recurrence refers to the cancer coming back and spreading to a different part of the body, which can happen even years after the original diagnosis and treatment.

Metastatic Breast Cancer: The Basics
Metastatic breast cancer , is breast cancer that has spread beyond the breast and the surrounding lymph nodes to other parts of the body, Nancy Lin, MD, an oncologist who specializes in breast cancer at Dana-Farber Cancer Institute in Boston, told Health. Approximately 30% of breast cancer patients will develop metastatic breast cancer following an initial earlier-stage diagnosis, according to a review in the Journal of Internal Medicine. Meanwhile, the American Society of Clinical Oncology reports that just 6% of women have metastatic breast cancer when they are first diagnosed.
“Basically what’s happening is the cancer cells are growingthey get into the bloodstream which then allows them to travel to distant sites ,” Evelyn Toyin Taiwo, MD, hematologist and oncologist at Weill Cornell Medicine and NewYork-Presbyterian Brooklyn Methodist Hospital, told Health. Metastatic breast cancer cells most often take up residence in the bones, liver, lungs, and brain, said Dr. Taiwo, but they can spread anywhere in the body.

From Cured To Stage 4
Others, like Teri Pollastro, a 54-year-old stage 4 patient from Seattle, respond surprisingly well.
Diagnosed with early stage ductal carcinoma in situ in 1999, Pollastro underwent a mastectomy but did not receive chemotherapy, radiation or tamoxifen, since her cancer was ER negative.
âThey used the C-word with me, they told me I was cured,â she said. âEvery time I went back to my oncologist, he would roll his eyes at me when I had questions.â
In 2003, Pollastro switched to Seattle Cancer Care Alliance where she saw Dr. Julie Gralow, a breast cancer oncologist and clinical researcher at Fred Hutchinson Cancer Research Center. Gralow discovered Pollastroâs cancer had metastasized to her liver.
âMy husband and I were in shock,â said Pollastro of her mets diagnosis. âYou donât go from being cured to stage 4.â
Pollastro went on Herceptin, a type of immunotherapy for women with HER2-positive metastatic breast cancer, and did six months of chemotherapy.
âI felt better right away with the treatment,â she said. âBut the problem is, it stopped . Thatâs what you can expect with mets. And thereâs always some residual cancer. And that starts percolating.â
And along with mets, she also had to deal with many misconceptions regarding her disease.
The Mercer Island, Washington, mother of two, who often counsels newly diagnosed patients, sometimes even found it difficult to relate to early stage breast cancer survivors.
Clinical Trials Are A Promising Treatment Option
For people with advanced stages of cancer, clinical trials can be considered the gold standard of treatment. I recommend clinical trials highly, says Rosen. You get access to medication and treatment that you normally wouldnt have.
A clinical trial could even have positive results on your cancer. We are living in an exciting time for cancer treatment, says Kimmick. There are myriad new drugs coming out that will improve the lives of all women with breast cancer, both metastatic and early stage.
However, its important to be realistic about the potential outcome of your trial. Rosen was recently enrolled in a clinical trial in which the medication proved toxic for her. But she has no regrets about participating. It feels like Im helping researchers who are working on cures for cancer, she says. When I had a bad reaction to the drug, they were able to put my side effects in their study. I feel like I did help, and that makes me happy.
People interested in joining a clinical trial for treatment should talk to their doctor about options that might be good for them.

How Will Hospice Help
Many people are amazed at the help available when hospice is instituted. In addition to care from the team, hospice most often provides a hospital bed, oxygen, and any equipment or medications needed. This can save a lot of running around for your family and make you as comfortable as possible.
Many people want to spend their last days at home, surrounded by loved ones. With hospice care, the police do not need to be called, as they typically do with any unattended death. Your family can spend time with you until they wish to call the funeral home.

Living With Stage : The Breast Cancer No One Understands
Editor’s note: We’re bringing back this piece from October 2014 for Metastatic Breast Cancer Awareness Day and to honor Jody Schoger, featured in the story. Schoger died of metastatic breast cancer in May. Want to learn more about MBC? Look for our tweets at the Northwest Metastatic Breast Cancer Conference this Saturday at Fred Hutch.
A no-nonsense Texan of 60 years, Jody Schoger* has a very no-nonsense way of educating people about her metastatic breast cancer.
âSomeone will say, âWhen are you done with treatment?â and Iâll tell them, âWhen Iâm dead,ââ said Schoger, a writer and cancer advocate who lives near Houston. âSo many people interpret survivorship as going across the board. That everybody survives cancer now. But everybody does not survive cancer.â
An estimated 155,000-plus women in the U.S. currently live with âmets,â or metastatic breast cancer. This type of cancer, also called stage 4 breast cancer, means the cancer has metastasized, or traveled, through the bloodstream to create tumors in the liver, lungs, brain, bones and/or other parts of the body. Between 20 and 30 percent of women with early stage breast cancer go on to develop metastatic disease. While treatable, metastatic breast cancer cannot be cured. The five-year survival rate for stage 4 breast cancer is 22 percent median survival is three years. Annually, the disease takes 40,000 lives.

Will I Need More Than One Treatment For Metastatic Breast Cancer
Medications are important for metastatic breast cancer to help control its spread. Resistance to therapies may develop, which can lead your care team to recommend a change in treatment.
When you start a treatment regimen, you and your care team will see how:
- The cancer responds to the therapy.
- The side effects impact you.
If the treatment isnt working or the side effects are unbearable, your care team can discuss switching the treatment method. They may recommend a different drug, dosage or schedule.
There are many treatments available. If one therapy isnt working for you for whatever reason, there is usually another one you can try.
Plans Have To Be Flexible
My energy is unpredictable, says Sendelbach. I literally never know how Im going to feel from one day to the next. Its so hard to make plans because if I say yes to something thats two weeks away, the day of, I could wake up and feel absolutely horrible.
When someone with metastatic breast cancer declines an invitation or cancels at the last minute, its most likely not because they dont want to be there. Says Sendelbach, We physically cant do it.
Silberman agrees. Ive been going through for a long time, she says, and Ive had friends drop away. Because of MBC and my treatments, its hard for me to be reliable.

Stage 4 Breast Cancer
Advanced breast cancer refers to cancer that has spread beyond the breast to other parts of the body. This process of spreading from the original location to a new location is known as metastasis.
The most common places of breast cancer spread include the bones, liver, lung, and brain. However, breast cancer may also spread to other organs.
The majority of women who are diagnosed with metastatic breast cancer have been diagnosed with an earlier stage of breast cancer before. In this instance, the original cancer in the breast is called the primary cancer. However, for some women, a diagnosis of metastatic breast cancer may be their first diagnosis of cancer .
Symptoms Of Metastatic Breast Cancer
The symptoms of stage 4 breast cancer depend on the location of the cancer and where it has spread in your body.
- If breast cancer has spread to your bones, you may notice a sudden new bone pain. Breast cancer most commonly spreads to your ribs, spine, pelvis, or arm and leg bones.
- If it has spread to your brain, you may experience headaches, vision or speech changes, or memory problems.
- Breast cancer that has spread to your lungs or liver usually causes no symptoms.
The main treatments for stage 4 breast cancer are targeted drug therapies that destroy cancer cells wherever they are in your body.
These treatments may include:
- hormone therapy, which stops or slows the growth of tumors by preventing your body from producing hormones or interfering with the effect of hormones on breast cancer cells
- chemotherapy, where drugs given orally or through an IV travel through your bloodstream to fight cancer cells
- immunotherapy, which uses drugs that stimulate your immune system to destroy cancer cells
- a combination of these therapies
In some cases, surgery or radiation therapy may be used to treat stage 4 breast cancer.
The following are the common treatment options for different types of stage 4 breast cancer.

Treatment For Physical Symptoms
The American Cancer Society urge that a person should not have to endure pain in the final months and days of life.
Many people find relief with opioid medications, but these can cause side effects such as fatigue and constipation. A person may use opioids in combination with other pain relief medications, such as acetaminophen or ibuprofen.
Other drugs, such as antidepressants and antiseizure medications, can also treat certain types of pain.
Doctors can also prescribe medications for nausea and vomiting. Some drugs for treating nausea can make a person drowsy. However, these drugs may help people eat and drink more or simply make it easier for them to function and interact with other people.
Myth #: Metastatic Breast Cancer Is Curable
Whether metastatic breast cancer is someones first diagnosis or a recurrence after treatment for earlier-stage breast cancer, it cant be cured. However, treatments can keep it under control, often for months at a time. People with MBC report fielding questions from family and friends such as, When will you finish your treatments? or Wont you be glad when youre done with all of this? The reality is they will be in treatment for the rest of their lives.
A typical pattern is to take a treatment regimen as long as it keeps the cancer under control and the side effects are tolerable. If it stops working, a patient can switch to another option. There may be periods of time when the cancer is well-controlled and a person can take a break. But people with MBC need to be in treatment for the rest of their lives.
As member of our Community at Breastcancer.org Vlnprh of Wisconsin comments: The vast majority of people have no idea what MBC treatment involves. They somehow think that you will undergo something similar to early-stage patients surgery, radiation, chemo, whatever and then be done. They want to see you as a pink-tutu-wearing cheerleader jumping up and down declaring that you have beaten this disease

I think its been a good thing to change the way I live my life I find it much easier to focus on what is really important to me. Fiona
The women talk about how priorities shift after a metastatic breast cancer diagnosis. Some women share how work continues to bring meaning and purpose to their lives, while another speaks of how the diagnosis prompted her to spend more time with family.
Myth #: People With Metastatic Breast Cancer Look Sick And Lose Their Hair
You dont look sick. You look so well. Why do you still have your hair? Are you sure you have cancer? These are comments that people with MBC report hearing. But there are many treatment options besides chemotherapy, and people often appear well while taking them.
As NancyHB comments: Id much rather be a poster child for how sometimes we can live with, rather than die from, MBC at least for a while. Instead, I find myself defending against people who are increasingly becoming impatient with my lack of cancer-patient appearance. Im grateful for this time of feeling good, and theyre harshing my buzz.
Some people with MBC report that they actually look better than they feel while in treatment. So they sometimes have to let family and friends know that even though they appear fine, they dont feel well.
Shetland Pony notes: If she looks good, she is good. Nope. Many of us suffer from the invisible disability of fatigue. I would venture to say every available treatment causes us some level of fatigue. We struggle to keep up. It may look like we are doing the bare minimum when we are really giving it our all.
JoE777 of Texas adds: The new normals advertised about therapies on TV are deceiving about the side effects. They talk about side effects while women are skipping through life. not looking to show the harsh side effects but think there is something wrong with me that my life is not like that.

Can Stage 4 Breast Cancer Go Into Remission
Stage 4 breast cancer can go into remission, meaning that it isnt detected in imaging or other tests. Pathological complete remission indicates a lack of cancer cells in tissues removed after surgery or biopsy.
But its rare to take tissue samples while treating stage 4 breast cancer. This could mean that although treatment has been effective, it hasnt completely destroyed the cancer.
Advances in stage 4 breast cancer treatments are helping to increase the length of remission.
Triple Negative Breast Cancer
With this type of breast cancer, the breast cancer cells dont have ER+ or PR+ receptors. They dont overproduce the HER2 protein, so hormone therapy isnt very effective.
Instead, triple negative stage 4 breast cancer is usually treated with chemotherapy. Radiation therapy may also be an option, depending on the site of metastasis.

Is Metastatic Cancer Always Terminal
This cancer stage has high mortality risk. However, in most cases, stage 4 or metastatic cancer is not always terminal. It is all depending on the spread area and case. On the other hand, it is also the stage where more advanced and aggressive treatment is necessary to kill the cancer cell.
Terminal cancer refers to a cancer case that is impossible to cure. This case mostly will result in the death of the patient. Therefore, the treatment for terminal cancer is only to control the spread and ease the patients pain. The curing process is difficult to do. So, it is the period when doctors and patients families prepare for the worst.
Despite its obvious result, the medical world still sets the standard for the patients survival likelihood. And, to learn more about that matter, you can continue reading. We will start talking about our main topic here, the stage 4 cancer life expectancy.
