How Fast Does Cancer Spread? Without Treatment, Growth Rate, More


Our bodies are made up trillions of cells. normally, newfangled cells replace old or damaged cells as they die off. sometimes, a cell ’ s DNA becomes damaged. The immune system can broadly control a small numeral of abnormal cells from far price to our bodies. Cancer occurs when there are more abnormal cells than the immune system can handle. rather of dying, abnormal cells continue to grow and divide, piling up in the form of tumors. finally, that out-of-control growth causes the abnormal cells to invade surrounding tissues.

There are more than 100 types of cancer named for the tissues or organs where they originate. All have the ability to spread, but some are more aggressive than others. Continue reading to learn how cancer spreads, how it ’ s staged, and how versatile treatments work.

Why cancer spreads

Cancer cells don ’ metric ton respond to signals telling them it ’ south time to die, so they continue quickly dividing and multiplying. And they ’ ra very good at hiding from the immune system. When cancer cells are still contained in the tissue where they developed, it ’ s called carcinoma in situ ( CIS ). once those cells break outside the tissue ’ mho membrane, it ’ randomness called invasive cancer. The go around of cancer from where it started to another invest is called metastasis. No matter where else in the body it spreads, a cancer is even named for the place it originated. For example, prostate cancer that has spread to the liver is still prostate cancer, not liver cancer, and discussion will reflect that. While solid tumors are a have of many types of cancer, that ’ s not always the case. For model, leukemias are cancers of the blood that doctors refer to as “ liquid tumors. ” precisely where cancer cells will spread future is pendent on their location in the body, but it ’ s probable to spread nearby first. cancer can spread through :

  • Tissue. A growing tumor can push through surrounding tissues or into organs. Cancer cells from the primary tumor can break away and form new tumors nearby.
  • The lymph system. Cancer cells from the tumor can enter nearby lymph nodes. From there, they can travel the entire lymph system and start new tumors in other parts of the body.
  • The bloodstream. Solid tumors need oxygen and other nutrients to grow. Through a process called angiogenesis, tumors can prompt the formation of new blood vessels to ensure their survival. Cells can also enter the bloodstream and travel to distant sites.

What stages have to do with cancer spread

Cancers are staged according to tumor size and how far it has spread at the time of diagnosis. Stages aid doctors decide which treatments are most probable to work and give a general expectation. There are different types of staging systems and some are specific to certain types of cancer. The following are the basic stages of cancer :

  • In situ. Precancerous cells have been found, but they haven’t spread to surrounding tissue.
  • Localized. Cancerous cells haven’t spread beyond where they started.
  • Regional. Cancer has spread to nearby lymph nodes, tissues, or organs.
  • Distant. Cancer has reached distant organs or tissues.
  • Unknown. There’s not enough information to determine the stage.

Or :

  • Stage 0 or CIS. Abnormal cells have been found but have not spread into surrounding tissue. This is also called precancer.
  • Stages 1, 2, and 3. The diagnosis of cancer is confirmed. The numbers represent how large the primary tumor has grown and how far the cancer has spread.
  • Stage 4. Cancer has metastasized to distant parts of the body.

Your pathology report may use the TNM stag organization, which provides more detailed data as follows : T: Size of primary tumor

  • TX: primary tumor can’t be measured
  • T0: primary tumor can’t be located
  • T1, T2, T3, T4: describes the size of the primary tumor and how far it may have grown into surrounding tissue

N: Number of regional lymph nodes affected by cancer

  • NX: cancer in nearby lymph nodes can’t be measured
  • N0: no cancer is found in nearby lymph nodes
  • N1, N2, N3: describes the number and location of lymph nodes affected by cancer

M: Whether cancer has metastasized or not

  • MX: metastasis can’t be measured
  • M0: cancer hasn’t spread to other parts of the body
  • M1: cancer has spread

so, your cancer stage might look something like this : T2N1M0 .

Tumor growth and spread

Benign tumors

Benign tumors are noncancerous. They ’ re covered with normal cells and aren ’ thyroxine able to invade nearby weave or other organs. Benign tumors can cause a few problems if they :

  • are large enough to press on organs, cause pain, or are visually bothersome
  • are located in the brain
  • release hormones that affect body systems

benign tumors can normally be surgically removed and are improbable to grow back.

Malignant tumors

cancerous tumors are called malignant. Cancer cells form when DNA abnormalities cause a gene to behave differently than it should. They can grow into nearby tissue, spread through the bloodstream or lymph system, and spread through the body. malignant tumors tend to grow faster than benign tumors.

How treatment works to stop cancer spread

broadly speaking, it ’ sulfur easi einsteinium radius to treat cancer before it has the opportunity to spread. Treatment depends on the particular type of cancer deoxyadenosine monophosphate well as the stage. In many cases, treatment will consist of more than one therapy .


Depending on the type of cancer you have, surgery may be the first-line treatment. When operation is used to remove a tumor, the surgeon besides removes a little allowance of tissue around the tumor to lower the chances of leaving cancer cells behind. operating room can besides help stage the cancer. For exercise, checking the lymph nodes near the chief tumor can determine if cancer has spread locally. You may besides need chemotherapy or radiation sickness therapy following operation. This may be an add caution in character any cancer cells were left behind or have reached the blood or lymph system. If a tumor can ’ triiodothyronine be completely removed, your surgeon may hush remove share of it. This can be helpful if the tumor was causing pressure on an organ or causing annoyance .

Radiation therapy

radiation sickness uses high-energy rays to kill cancer cells or slow their emergence. The rays target a specific area of the body where cancer has been found. radiation can be used to destroy a tumor or to relieve pain. It can besides be used after operating room to target any cancer cells that may have been left behind .


Chemotherapy is a systemic treatment. Chemo drugs figure your bloodstream and travel throughout your torso to find and destroy quickly dividing cells. Chemotherapy is used to kill cancer, slow its growth, and reduce the casual that newly tumors will form. It ’ randomness useful when cancer has spread beyond the basal tumor or if you have a type of cancer for which there are no target therapies .

Targeted therapy

Targeted therapies depend on the particular type of cancer, but not all cancers have targeted therapies. These drugs attack particular proteins that allow tumors to grow and spread. angiogenesis inhibitors interfere with the signals that allow tumors to form raw blood vessels and continue growing. These medicines can besides cause already existing blood vessels to die, which can shrink the tumor. Some types of cancer, like prostate and most breast cancers, need hormones to grow. Hormone therapy can stop your body from producing the hormones that feed the cancer. Others stop those hormones from interacting with cancer cells. Hormone therapy besides helps to prevent recurrence .


Immunotherapies boost the might of your own soundbox to fight cancer. These drugs can strengthen your immune system and help it recognize cancer cells .

Stem cell or bone marrow transplant

A stem cell transplant, sometimes called bone kernel transplant, replaces damaged blood-forming cells with healthy ones. The operation takes place following large-dose chemotherapy or radiation sickness therapy to kill cancer cells and to stop your stalk cells from producing cancerous cells. Stem cellular telephone transplants can be used for several types of cancer, including multiple myeloma and some kinds of leukemia.

The takeaway

Cancer international relations and security network ’ t a individual disease. There are many types — and subtypes — of cancer. Some are more aggressive than others, but there are many variables that lead to different cancer characteristics. Your oncologist can give you a better agreement of the distinctive behavior of a certain kind of cancer based on the specifics of your pathology report .
