Organismal Biology is an active-learning class where you will explore the evolutionary history of all life on Earth through the lenses of development and reproduction, signaling and communication, and physiology and organ systems. As we explore the diversity of life on Earth, you'll be able to identify biological patterns and explain how you are both similar to and different to the breadth of diversity of life on Earth.

A growth of a cancerous brain tumor is basically  the cancer spreading from the brain to another organ in the body.

What other systems do brain tumors effect?

# data[].attributes.body
Brain tumors that are cancerous can effect all the human organ systems since the cancer can spread to the other organs that will most probably effect their system.

# data[].attributes.body
No one knows the cause of brain tumors but children that receive radiation to the head have a higher chance of getting brain tumors when they are adults.

# data[].attributes.body
Some of the brain tumors that are cancerous start in the brain then spread to the spinal cord and that can effect the CNS so it may press on a peripheral nerve and that can lead to either CNS symptoms like balance problems and decreased memory or PNS symptoms like numbess and constipation.

Most often the cause of metastasis is lung cancer but it can also be breast cancer, melanoma or genitourinary tract cancers

# data[].attributes.body
Brain metastasis is a cancer that has been metastasized ( spread ) to the brain from another part of the body so its a secondary brain tumor.

# data[].attributes.body
To treat brain tumors you can do multiple things. You can get surgery, radiotherapy and chemotherapy.

Cancerous tumors that spread to the brain like metastatic brain tumors can effect the central nervous system.

Both primary and secondary brain tumors can be life threatening.  Contained in our skull our brain can't expand to make room for a growing mass.

What are the symptoms for metastatic brain tumors?

What are the symptoms for metastatic brain tumors?

# data[].attributes.body
Some of the symptoms are numbness, seizures, headaches, imbalance and short term memory difficulty.

# data[].attributes.body
Metastatic brain tumors start off as cancer somewhere else in the body and spreads to the brain. They form where cancer cells are carried though the blood stream and to the brain.

# data[].attributes.body
Malignant brain tumors spread quickly and have strange boundaries. Even though they're often called brain cancer, its is not because it doesn't spread to different organs that aren't the brain and spine.

# data[].attributes.body
Benign brain tumors can grow slowly and it barely spreads. Even though its cells aren't malignant, benign tumors can be life threatening.

# data[].attributes.body
A primary brain tumor is when the unusual growth starts in the brain and usually doesn't spread to other parts of the body.  A primary brain tumor can either be  benign or malignant.

# data[].attributes.body
A brain tumors takes  place in the nervous system. A brain tumor is when  unusual cells form in the brain. There are 120 different types of brain tumors.
