An Overview of Cancer

An Overview of Cancer

Cancer is second only to cardiovascular disease as the leading cause of death in the Western world.
Although Cancer is primarily a disease of the elderly with more than 60% of deaths from cancer occurring in those over the age of 65, cancer can strike even the youngest of children.

Cancer appears to occur when the growth of cells in the body is out of control and cells divide too rapidly. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue.

Most common sites are:
Prostrate 24%
Breast 13%
Lung 13%
Colon and Rectum 9%
Bladder 3%
Uterus 2.5%

The cause of Cancer is believed to be a combination of genetic factors and outside carcinogens such as tobacco, viruses, infection, asbestos, vinyl chloride, inappropriate diet.

Cancer often has no specific symptoms, so it is important that you limit your risk factors and undergo appropriate cancer screening. The signs and symptoms will depend on where the cancer is, the size of the cancer, and how much it affects the nearby organs or structures.

If a cancer spreads (metastasizes), then symptoms may appear in different parts of the body. As a cancer grows, it begins to push on nearby organs, blood vessels, and nerves. If the cancer is in a critical area, such as certain parts of the brain, even the smallest tumor can cause early symptoms.

But sometimes cancers start in places where it does not cause any symptoms until the cancer has grown quite large. Pancreatic cancers, for example, do not usually grow large enough to be felt from the outside of the body.
By the time a pancreatic cancer causes these signs or symptoms, it has usually reached an advanced stage.

A cancer may also cause symptoms common to many other problems, such as; fever, fatigue and weight loss. This may be because the cancer uses up much of the body s energy or it may cause the release of substances which affect metabolism.

Some lung cancers make hormone-like substances that affect blood calcium levels, affecting nerves and muscles and causing weakness and dizziness.

It is important to know what some of the general (non-specific) signs and symptoms of cancer are, but remember that having any of these does not mean that you have cancer.

Most cancers can be treated and some cured, depending on the specific type, location, and stage. The earlier the cancer is found, the better the prognosis.

A good example of the importance of finding cancer early is melanoma skin cancer. Skin cancer can be easy to remove if it has not grown deep into the skin, and the 5-year survival rate (percentage of people living at least 5 years after diagnosis) at this stage is nearly100%.

Screening for breast cancer with mammograms has been shown to reduce the average stage of diagnosis of breast cancer in a population.
Colorectal cancer can be detected through fecal occult blood testing and colonoscopy, which reduces both colon cancer incidence and mortality, presumably through the detection and removal of pre-malignant polyps.
Similarly, cervical cytology testing (using the Pap smear) leads to the identification and excision of precancerous lesions.
Testicular self-examination is recommended for men beginning at the age of 15 years to detect testicular cancer.

SIGNS and SYMPTOMS

Pain may be an early symptom with some cancers such as bone cancers or testicular cancer.

Long-term constipation, diarrhea, or a change in the size of the stool may be a sign of colon cancer.

Pain with urination, blood in the urine, or a change in bladder function (such as more frequent or less frequent urination) could be related to bladder or prostate cancer.

Skin cancers may bleed and look like sores that do not heal.

A long-lasting sore in the mouth could be an oral cancer and should be dealt with right away, especially in patients who smoke, chew tobacco, or frequently drink alcohol.

Sores on the penis or vagina may either be signs of infection or an early cancer, and should not be overlooked.

Unusual bleeding can happen in either early or advanced cancer.

Blood in the sputum (phlegm) may be a sign of lung cancer.

Blood in the stool (or a dark or black stool) could be a sign of colon or rectal cancer.

Blood in the urine may be a sign of bladder or kidney cancer.

A bloody discharge from the nipple may be a sign of breast cancer.

Many cancers can be felt through the skin, mostly in the breast, testicle, lymph nodes (glands), and the soft tissues of the body. A lump or thickening may be an early or late sign of cancer.

While they commonly have other causes, indigestion or swallowing problems may be a sign of cancer of the esophagus, stomach, or pharynx (throat).

A cough that does not go away may be a sign of lung cancer.

A cancer may be suspected for a variety of reasons, but the definitive diagnosis of most malignancies must be confirmed by histological examination of the cancerous cells by a pathologist.

TREATMENT

Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy.

Radiation therapy may be used to treat almost every type of solid tumor, including cancers of the brain, breast, cervix, larynx, lung, pancreas, prostate, skin, stomach, uterus, or soft tissue sarcomas.

Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.

Contemporary methods for generating an immune response against tumours include intravesical BCG immunotherapy for superficial bladder cancer, and use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma patients.

Pain medication, such as morphine and oxycodone, and anti-emetics, drugs to suppress nausea and vomiting, are very commonly used in patients with cancer-related symptoms. transmission and disease.

Advances in cancer research have made a vaccine designed to prevent cancer available. The vaccine protects against four HPV types, which together cause 70% of cervical cancers and 90% of genital warts.

The consensus on diet and cancer is that obesity increases the risk of developing cancer. The cancer-fighting components of food are also proving to be more numerous and varied than previously understood, so patients are increasingly being advised to consume fresh, unprocessed fruits and vegetables for maximal health benefits.

Question and Answer


CANCER??????????????????????????????????????????????????
went to a specialist after months of severe neck pain…and on the Mri it showed a white lump on my neck. The dr didn't seem concerned and had me have a ct scan. He said it was a benign hemangioma and nothing to worry about. This lump has been killing me, feeling like it was twisting my neck, last night I was up till 7:30 am. I also developed chest pain..and pain in my left side, could that be the spleen? I don't know what the problem is, and the dr's don't have a clue either…any ideas? Could this be cancer? Aren't malignant tumors not painful and benign ones painful? If it isn't cancer…then what?? I had lyme disease last year but was treated…is it possible I wasn't on medication long enough? The tick bite has gotten red again…from last year?? Or is this just a coincidence?

I also have severe burning on my left side, by the ribs..and what I assume is the spleen looks enlarged. I have joint pain, and my back burns so much that I thought I had a heating pad on lol…my mom said that means inflamation of the kidneys??? Is this cancer? Lyme disease? IDK
I had lyme disease last year, but was treated. I have joint pain,and the bite where the tick bit turns red on occasional days, but that was last year? I have had some headaches and hearing loss…LYME DISEASE?

Do you want someone to read the book for you as well? Perhaps also write up a cheat sheet, so you will have a chance of passing the test, and then get your degree?

What will happen when someone enters your office and says "I have cancer, how am I going to survive ovarian cancer" Tell them after you get back to reading your second year college book, you will have an answer? Their life will be in your hands. If you can not handle this, and want to spend your time on vacation, well drop out of school, so you will not let anyone die from your lack of knowledge on the subject that you are (or someone else is) spending a lot of money for you to learn.

By the way, if you have been selling your old college books, all I can ask is why? You learned much information from them, and while in 5 years they will be a little out of date, they will still provide the basic research that you will need. I would save them for at least 10 years, so you can use them to quickly look up information, and refresh your memory. 25 years from now, you can look at the information and say "Back in 2006, they actually still used toxic chemotherapy to kill cancer, when we all know now that was so toxic to the healthy cells."

I have an old 1955 almanac, and it describes Asbestos in the most endearing terms, how it saves many lives per year in fire safety equipment, and how HEPA air filters are made out of asbestos to prevent radioactive elements from passing through the fine weave asbestos filters.

I have a feeling in 2025 we will be embracing Chemotherapy as much as we love spraying our ceilings with asbestos today. Both are very toxic, and cancer is so easy to kill with high PH therapy.

Google 'Dr. Otto Warburg', he discovered it is easy to kill cancer, and even won a Nobel Prize for that research.

But remember that the test that you take will be based on what was written in your textbooks, even if the textbook is from 5 years ago, and has much outdated research in it. The "Correct answer" will be what the author based his book on.

It looks like you have a lot of reading to do.

woulda been funny if the dirt flew in his face lmao

The BBC use buly boy balliffs to ensure they get their money from single parent mothers who simply cannot afford the hundreds of pounds they’re being asked for, often seizing goods from families with very liitle, in order to pay grossly inflated wage packets. Well done BBC.

I do check them twice amonth but it's hard for me to identify exactly what I'm feeling for.My mom was diagnosed with breast cancer at 32 years old and passed away at 35,I'm 34 so I am concerned

You have discovered that dream dictionaries are pretty worthless, except for crushing cockroaches

Since I know nothing of your person situation, I am going to be vague and general.

The oven may represent a change one has to go through. One could say it is a kind of purification ritual (as it was done at the church).
The clothes could also mean a change of how you look as well, to go with the "new you".

Are you looking to change how people see you?

http://fox.com/house/recaps/ this will give you the info you need. for any episode.

Or, you can rent them at blockbuster and put on the closed captioning, that works too.

Hope this helped. Have a good day, Fellow house-aholic

is a small book of immense help.
You will have to read a few references given in the book also

Unfortunately, it sounds normal with the blockage and the recent hysterectomy and other surgeries. Best wishes.
