Cancer

Malignantis cancerous. Malignant tumors can invade and destroy nearby tissue and spread to other parts of the body.

Benign is not cancerous. Benign tumors may grow larger but do not spread to other parts of the body.

I'd just tell them outright... maybe in a manner similar to how James Stewart's character told John Wayne's character he had cancer in The Shootist. Yeah, that's how I'd do it.

But, the reality of it is that you know the person you'll be telling this to - your judgment on how to go about this is going to be the best one to use.

Best of luck to you.

Epidemiological studies suggested an association between isopropyl alcohol and paranasal sinus cancer; however, subsequent analysis suggests that the "strong-acid" process used to manufacture isopropyl alcohol may be responsible for these cancers [ACGIH 1991]. The International Agency for Research on Cancer has concluded that the evidence for the carcinogenicity of this process is adequate but that the evidence for isopropyl alcohol itself is inadequate [IARC 1987].

u have to have a card called the medical marijuana card to be able to smoke it legally

Answer

Although smoking or ingesting marijuana is illegal in the USA (saving some medical exemptions) as yet no person's over the age of 150 have been prosecuted.

There are a number of strategies that can reduce the risk of cancer:
1. Avoid smoking
2. Get vaccinated against HPV and hepatitis B
3. Maintain a healthy weight and diet
4. Exercise daily
5. Use alcohol moderately, if at all
6. Use sunblock and other strategies for sun prevention
7. If you have a baby, breastfeed
8. Complete routine recommended screenings for cervical cancer, breast cancer, and colon cancer.
9. Watch for warning signs of cancer, including stool changes, skin changes, sores that won't heal, lumps in the breasts or testicles, or chronic cough.

The survival rates for colon cancer depend on in which stage the cancer is originally detected. If detected at an early stage, the five year survival rate can be as high as 90%, however if the cancer goes undetected into a distant stage, the five year survival rate can drop dramatically, becoming 12%.

This is a very rare cancer which starts in the lining of the abdominal cavity, the peritoneum. Usually in females, peritoneal cancer is caused from metastasis from ovarian cancer, but in females where the ovaries have been removed, it can be primary, which means the site of origin of the cancer (It didn't come from anywhere else."

A brain tumor can have an unlimited amount of effects. Not only it depends if the tumor is localized or spreads, but it also depends on the specific brain areas it affects. Also, even if a brain tumor is localized, since it is growing, a brain tumor will apply more and more pressure on the surrounding brain areas responsible for different cognitive domains such as memory, language, sensing, decision making...etc...

The chemicals of the tumor may also affect how the person interacts with others. They may develop a temper, be angry, have trouble understanding and lose their concept of time.

you better check for doctor...

It is never good for your lungs to inhale smoke; the lungs get dirty and it is difficult to expel the dirt by the normal function of lung cilia, when the dirt is constantly being replenished by continued smoking. Of course, cannabis is not only consumed by smoking. You can also use it to brew tea, which avoids any harm to the lungs although it may still constitute an illegal use of a recreational drug - unless you have a valid medical need for it.

Here are the lifetime chances of getting cancer and dying from cancer:

American Cancer Society Reference Information

http://www.cancer.org/docroot/CRI/content/CRI_2_6x_Lifetime_Probability_of_Developing_or_Dying_From_Cancer.asp

And here is the annual rate of cancer deaths in the U.S.:

556,902 cancer deaths in the U.S. in 2002

287,973,924 people in the U.S. in 2002

=

556,902 / 287,973,924 = 0.193%

in 2003, approximately 12,200 women would be diagnosed with cancer of the cervix and 4,100 women would die of the disease.

When your body's cells replicate, they go through 3 phases. The first being the growth phase. The second being synthesis or replication of the DNA. The third being the phase where it checks over the replicated DNA to check for any errors (or spell check kind of). Cancer is when those body cells that are being replicated, are replicating way too fast for them to go through the 3rd phase and get checked for errors. Usually, when they are replicating this fast, there is some sort of mutation that is causing them to replicate this quickly.

When these cells skip the spell check, they have a mutation and this mutation causes the mutated DNA to take over all of the normal DNA. If the cancer is caught early enough, then there are technologies that can get rid of the small amount of mutated DNA but if noticed too late, the cancer cells have already taken over that persons body, and it would take some extensive treatment to even attempt to get rid of all the cancer cells..

Hopefully this helped answer your question. :)

Well some people say cancer is dangerous in any stage other say if you operate as quick as you can before it goes to another stage it'll be fine.

Cancer is triggered when there is a malfunction in the reproduction of cells. Either there is too much of something or not enough, causing the malfunctioning cells to constantly reproduce, which is later formed into what is known as a tumor.

even though it is a man it could still very well be breast cancer but it could also be nothing. I recommend you go to the doctor to get it looked at.

Chlorofluorocarbons (cfc) are a type of halogenated hydrocarbon in which both clorine and fluorine atoms replace some of the hydrogen atoms. CFSs have brought about thinning of the Earth's ozone shield, which protects terrestial life from dangerous effects of ultraviolet radiation. More cases of skin cancer are expected to occur due to depletion of ozon layer. Answer is Chlorofluorocarbons.

Yes!! Of course they can!! Today's radiotherapy machines are know as Linear Accelerators which are electric and once they are shut off they are off no radiation leaks, or go anywhere. They do not have a live source, and you do not become radioactive when you are receiving radiation therapy.

You can't harm others, and you can't spread radiation to others. The only thing you can't do is be in the room with them when they are receiving the treatment.

Other than that being around family is a great way for the person with cancer to get better it picks up their spirits, and improves their quality of life.

The Lungs are usually viewed in two sections, the Gas Movement section, and the Gas Exchange section. The right lung is significantly larger, having three Lobes, than the left lung, with only two lobes. This is because the left ventricle of the heart sits slightly to the left side of the thorax taking some of the space the lung would otherwize have had. The lungs are withing a cavity in the thorax called the Pleural Cavity and are surrounded by a bouble membrane called the Pluaral Membrane. The inner layer of the pleural membrane is called the visceral layer and is continuous with the alveoli of the lung, the outer layer is called the perietal layer. To follow a gas molecule breathed in would take you first down the Bronchus (there is one on each side, for each lung) then through a network of Bronchioles until it came to an Alveolar Duct. Up to this poin has been purely the gas movement section and all but the both the bronchi and bigger bronchioles have carticalge arounf them and smoothe muscle to control airflow. The alveolar ducts lead into Alveolar Air Sacs that look very much like bunches of grapes. This is where the gas exchange takes place across the very thin cells of the sacs into (and out of) the blood. So maximise the volumes of gas exchanged means you require as much of a surface area as possible and the of all the alveoli together is aound the same as half a tenis court. There is always some air within the alveoli because if there wasnt the fluid lining them would cause such a great surface tension that the sacs would never open again.

Cancer cells and normal cells in lung tissue differ in several key aspects, primarily due to genetic mutations and alterations in cellular behavior that drive the development and progression of cancer. Here are some of the fundamental differences between cancer cells and normal lung cells:

Uncontrolled Growth and Division:

Cancer Cells: Cancer cells have lost the normal regulatory mechanisms that control cell growth and division. They divide and replicate at an abnormally rapid rate, leading to the formation of tumors.

Normal Cells: Normal lung cells follow a controlled and regulated process of growth and division, ensuring that new cells are produced only when needed.

Genetic Mutations:

Cancer Cells: Cancer cells often harbor genetic mutations or alterations in their DNA. These mutations can activate oncogenes (genes that promote cell growth) and inhibit tumor suppressor genes (genes that regulate cell division and prevent tumor formation).

Normal Cells: Normal lung cells have intact and functional DNA that maintains the proper balance between cell growth and cell death.

Loss of Apoptosis:

Cancer Cells: Cancer cells can evade apoptosis, which is a programmed cell death mechanism that eliminates damaged or abnormal cells. This allows cancer cells to survive and accumulate, contributing to tumor growth.

Normal Cells: Normal lung cells undergo apoptosis when they are damaged or no longer needed, ensuring proper tissue maintenance and homeostasis.

Invasion and Metastasis:

Cancer Cells: Cancer cells can invade surrounding tissues and spread to distant parts of the body through the bloodstream or lymphatic system, a process known as metastasis.

Normal Cells: Normal lung cells remain localized to their specific tissue and do not invade neighboring tissues or spread to other parts of the body.

Angiogenesis:

Cancer Cells: Cancer cells can stimulate the formation of new blood vessels (angiogenesis) to supply the growing tumor with nutrients and oxygen.

Normal Cells: Normal lung cells do not induce excessive angiogenesis unless needed for tissue repair or growth.

Cell Shape and Organization:

Cancer Cells: Cancer cells often have irregular shapes, sizes, and organization. They may form disorganized clusters within tumors.

Normal Cells: Normal lung cells have a specific and organized structure, contributing to the proper functioning of lung tissue.

Functionality:

Cancer Cells: Cancer cells do not perform the specialized functions of normal lung cells. Instead, they divert resources toward rapid proliferation.

Normal Cells: Normal lung cells carry out their specialized functions, such as gas exchange and mucus production, to maintain respiratory health.

These differences collectively contribute to the aggressive and destructive behavior of cancer cells compared to normal cells in lung tissue. Understanding these distinctions is crucial for developing targeted therapies that selectively target cancer cells while preserving the health and function of normal cells.

there is actually no cure for leukemia but what can prevent it from getting worse is keep doing exercises and eating right also make sure if you are going to get physical with someone that they have nothing at all because if they do you may worsen and you can end up dying within hours if not treated properly

For stage I (early/lymph node negative), which comprises 40-45% of total cases, the five-year survival is 85-95%.

Yes it is very possible to survive without a thyroid gland. After the surgerical removal of the thyroid, say abt 4-6weeks after, the patient is given a pill of radioactive iodine. After this, the patient would be on iodine pills for life so as to aid the production of the thyroid hormone which no humna can survive without. I hope Ive been able to answer your question.
