Risk Factors And Stages Of Throat Cancer
Smoking, excessive consumption of alcohol, and the use of chewing tobacco are the main risk factors for cancers of the mouth, throat, and voice box. Other probable causes include prolonged exposure to wood dust, paint fumes, and certain chemicals employed in metalworking, petroleum, plastics, and textile industries. An infection by HPV could also put a person at a risk of developing cancer of the hypopharynx.
The classification of the cancer into stages is based on the size and the extent to which cancer has spread. TNM staging system is one of the most commonly used staging system that helps in estimating the prognosis and the survival rate. It also helps the doctors ascertain the appropriate treatment options.
|TNM Staging for Throat Cancer
|Any T/Any N/M1
T refers to the size of tumor and extent to which it has spread. While TX implies that the primary tumor cannot be assessed, T1, T2, T3, and T4 indicate the increase in the size of the tumor.
N describes if the cancer has spread to the regional lymph nodes. N0 means that there is no lymph node involvement. N1, N2, and N3 indicate an increased lymph node involvement. NX means that the nearby lymph nodes cannot be assessed.
M refers to the spread of cancer to distant sites. M0 implies the absence of metastasis to distant organs, while M1 indicates the presence of distant metastasis.
Stage IT1 means that the tumor is 2 cm or less, while N0 and M0 rule out the regional lymph node involvement and distant metastases.
Do Throat Cancers Typically Recur
Whether a throat cancer recurs after treatment depends largely on the cancers stage at diagnosis. Those that were diagnosed at later stages are more likely to recur. With laryngeal cancer, for instance, the risk of recurrence over the first three years is 5 to 12% for stage 1 disease, and can be as high as 30% for stage 2 disease. For patients diagnosed later stages, the recurrence can be as high has 50% within the first five years. This means that this disease often recurs, and continued surveillance is necessary, she says.
Thats why patients should seek care for throat cancer at a comprehensive cancer center like Roswell Park. Due to the complexities of throat cancer, and the variation in diagnosis and treatment options, it’s important to go to a multidisciplinary cancer center like Roswell Park that provides patients with personalized treatment for their particular cancer, Dr. Wooten concludes. These options can include cutting-edge treatment to obtain the best possible outcomes for patients.
Breast Cancer Survival Rates By Country
Breast cancer is the most prevalent cancer in women worldwide. Survival is related to advances in treatment, detection through screening programmes and a greater awareness of the disease. Five-year survival for breast cancer has been improving in the UK over time, reaching 85.6% in 2010-2014. However, despite the relatively high breast cancer screening coverage when compared with several other OECD countries, the UK continues to lag behind in terms of survival. The United States reached the highest five-year breast cancer survival rate of 90.2% in 2010-2014, followed closely by Australia at 89.5% and Japan at 89.4%.

One of the factors that can affect a patients prognosis is whether the malignancy has metastasized . Once squamous cell carcinoma has spread beyond the skin, the five-year survival rate drops to less than 50 percent. Fortunately, its fairly rare for squamous cell carcinoma to metastasize. Plus, when metastasis does occur, the malignancy generally spreads slowly, with the majority of cases being diagnosed before the cancer has spread past the skins upper layer .
When staging squamous cell carcinoma, physicians will take a number of factors into account, one being the degree to which the cancer has already spread throughout the body. For example:
- At Stage 0, squamous cell carcinoma has not spread beyond the epidermis.
- At Stage 1, squamous cell carcinoma has spread deeper into the patients skin but has not entered any lymph nodes or healthy tissues.
- At Stage 2, squamous cell carcinoma still has not metastasized to any lymph nodes or healthy tissues, but displays at least one high-risk feature, which might include spreading into the skins lower layers or the nerves.
- At Stage 3, squamous cell carcinoma has spread into the patients lymph nodes but has not reached any other organs or tissues.
- At Stage 4, which is the most advanced stage, squamous cell carcinoma has spread to at least one distant organ .
What Is The Treatment For Throat Cancer
The treatment for throat cancer depends upon the extent and seriousness of the disease. As stated by the MD Anderson Cancer Center and others, treatment is tailored to the individual to provide him or her with the best chance for a successful outcome. Treatment strives to preserve the patient’s ability to eat, speak, and live a normal healthy life. Treatment plans for throat cancers usually include one or more of the following techniques: surgery, radiation therapy, chemotherapy, proton therapy, targeted therapies, and possibly participation in throat cancer clinical trials. Brief descriptions of the major components of throat cancer therapy are as follows:
Side effects of treatment vary from person to person. However, some of the most common side effects include

Tongue Cancer Survival Rate
These include the age of the patient, cancer stages, treatment taken and general health of a patient. If the patient is not suffering from other diseases, he has greater chance to survive from this disease. Knowing how to survive from this cancer is what you will learn through the facts below.
Tongue cancer is an infection of the areas around the tongue. Oral tongue cancer can be called as lesion or ulcer on the side of the tongue. Tongue usually becomes small and gray pink to red in color. There is a tumor that occasionally bleeds when bitten or touched. It may result to some problems with swallowing, talking or chewing.
These tongue cancer can be taken through excessive tobacco use or too much amount of alcohol drinking. This cancer is twice more prevalent in men than in women. Men usually smoke cigarettes and drink alcohol more often than women. However, having proper treatments would be helpful to eliminate cancer.
Causes of tongue cancer could vary which result to various symptoms. Pain in the tongue is one common symptom. Difficulty in swallowing and chewing is another sign of tongue cancer. Getting medical help is recommended once you feel these discomforts in the tongue.
What Is Throat Cancer
Throat cancer is a type of head and neck cancer that involves the pharynx and the larynx. The malignant tumor can develop in any part of the throat and termed according to the area of the throat that is affected such as the cancer of the nasopharynx which involves the upper portion of the throat. There are different types of cancer under throat cancer and each are termed accordingly. Throat cancer often affects people between the ages of 50 to 70 and predominantly affects the male gender. The peak onset of throat cancer is about age 64 to 66 years old with an increased risk to people who are smoking for a long time.
The throat is part of the digestive tract that can be located between the back of the tongue and the esophagus. It is composed of various blood vessels and pharyngeal muscles, the trachea and the esophagus. The only bones composed in the throat are the hyoid bone and the clavicle. The epiglottis is the fundamental feature of the throat which separates the esophagus and the trachea. It mainly acts by preventing food particles and liquid from entering the airway passage that can obstruct the air passage.

Squamous Cell Carcinoma Survival Rate
In general, the squamous cell carcinoma survival rate is very highwhen detected early, the five-year survival rate is 99 percent. Even if squamous cell carcinoma has spread to nearby lymph nodes, the cancer may be effectively treated through a combination of surgery and radiation treatment. Nevertheless, a patient who has been treated for squamous cell carcinoma in the past always faces the possibility of a recurrence, so lifelong monitoring to increase the chance of early detection is highly encouraged.
How Can I Protect Myself
You can reduce your risk of developing HPV or HPV-related throat cancer by taking a few precautions. Remember, HPV often doesnt cause any symptoms, so its important to protect yourself even if it seems like someone doesnt have HPV.
Follow these tips to reduce your risk:
- Use protection when having sex, including condoms and dental dams during oral sex.
- Avoid smoking and high alcohol intake, which may increase your risk of HPV-positive throat cancer if you already have HPV.
- Ask your dentist to check for anything unusual, such as patches of discoloration, in your mouth during regular teeth cleanings. Also, regularly check your mouth in a mirror for anything unusual, especially if you have oral sex often. While this cant prevent HPV-related cancer from development, it may help identify it earlier.
- If youre age 45 or under, talk to your doctor about the HPV vaccine if you havent previously received it.

Cancer Evaluation And Staging
The first step in decision-making for patients with cancer of the larynx is accurate diagnosis and staging. This requires adequate tissue biopsy and histologic interpretation by a pathologist. Generally, these cancers are not difficult to diagnose by the pathologist, but if the clinical presentation is unusual , or if the appearance is not typical or the growth is too slow or too fast, a second interpretation or re-biopsy may be warranted.
Because most treatment decisions are based on the size and extent of the cancer, precise direct visualization of the cancer is required. This usually involves examination with an endoscope in the physician’s office, which allows determination of vocal cord mobility and other dynamic features and also direct laryngoscopy with a microscope under anesthesia. The exact size, shape and depth of invasion can be better determined and a search for adjacent areas of pre-malignant or malignant change can be assessed in other areas such as the oral cavity, pharynx and esophagus. The larynx is connected with the back of the tongue and the lower swallowing passageways and so these areas must also be examined thoroughly.
What Is The Prognosis For Tonsil Cancer
When you learn that you have tonsil cancer, you may want to know about your prognosis — an estimate of how serious your disease is and what to expect in the future.
Keep in mind that not everyone wants to learn their prognosis, and that’s OK. But if you do, your doctor is the best person to ask. They do tests to see how large your cancer is and whether it has spread from your tonsils to another part of your body. The results will guide your treatment and help you learn about your outlook.

Interpreting Lung Cancer Survival Rates
Lung cancer is a very serious type of cancer and is often fatal. But thats slowly changing as research advances.
People who receive a diagnosis of early-stage lung cancer are surviving in growing numbers. According to the American Lung Association, about 541,000 people who received a lung cancer diagnosis at some point are still alive today.
If you receive a lung cancer diagnosis, your doctor may talk with you about probable survival rates. This number is a statistic based on large numbers of people with the same type and stage of cancer.
Your experience may be different. Your healthcare team can give you the best idea of what to expect based on your individual circumstances.
The Importance Of Throat Cancer Awareness
While throat cancers are not the most prevalent cancers in the United States, they still pose a danger to many, as the statistics above show. Education on the topic can help people combat risk factors, which include smoking and asbestos exposure. Creating a knowledge base of throat cancers can assist in critical conversations with your medical team.

Types Of Throat Cancer
The treatment plan and outlook for cancer will depend on the type. A biopsy will show what type of cancer cell is present.
The most common type of throat cancer is squamous cell carcinoma, which affects the flat cells lining the throat.
Two main categories of throat cancer are:
This cancer develops in the pharynx, the hollow tube that runs from behind your nose to the top of your windpipe. Pharyngeal cancers that develop in the neck and throat include:
- nasopharynx cancer
- oropharynx cancer
- hypopharynx cancer
This cancer forms in the larynx, which is your voice box. Cancer can develop in the:
- subglottis (part of the larynx below the vocal cords
much more likely to develop laryngeal cancer, according to the American Cancer Society .
Oral HPV is a sexually transmitted virus that affects around 10 percent of men and 3.6 percent of women, according to the Centers for Disease Control and Prevention . The CDC adds that HPV may account for around 70 percent of cases of oropharyngeal cancer in the United States.
Males are more likely to develop oropharyngeal or laryngeal cancers than females. While the overall rate is higher among white people, it is significantly higher for Black males compared with all females and with males from other races, according to

What Are The Survival Rates Seen In Throat Cancer Patients
Survival rates for different cancer types are calculated by making a note of the percentage of people who continue to remain alive and healthy after completing their treatment for the same stage and type of cancer, over a defined period of time, such as 5 years or 10 years. The available survival rate data cannot serve as an accurate indicator of how long each patient will live with their disease. However, it gives an understanding of the chances of success of a patients treatment, depending on the stage and type of diagnosis.
What Survival Rates For Tonsil Cancer Mean
When your doctor talks to you about your prognosis, they may use the phrase “5-year survival rate.” It’s a number based on research done on large numbers of people with oropharyngeal cancer — cancers of the tonsils and the base of the tongue.
Keep in mind that survival rates don’t predict what will happen to you in the future. Your outlook has to do with the kind of treatment you get and a host of things, like your age and overall health.
Five-year survival rates are the percentage of people with cancer who are alive 5 years or longer after their diagnosis. The overall 5-year survival rate for oropharyngeal cancer is 67%. That means 67Ã out of 100 people are alive 5 years after their diagnosis.
Researchers have also developed specific 5-year survival rates for oropharyngeal cancer that are based on whether and where the cancer has spread:
- Early-stage cancer that hasn’t spread: 85%
- Cancer that has spread to nearby lymph nodes, tissues, or organs: 68%
- Cancer that has spread to distant parts of the body: 40%
People with HPV-positive tonsil cancer have a 5-year “disease-free” survival rate of about 86%. Disease-free survival means they have no signs of cancer during the 5 years after their diagnosis.
It’s important to know that all these numbers come from studies that were done a few years ago. People who are diagnosed with tonsil cancer today may have a better prognosis thanks to new treatments.

Where Do These Numbers Come From
The American Cancer Society relies on information from the SEER* database, maintained by the National Cancer Institute , to provide survival statistics for different types of cancer.
The SEER database tracks 5-year relative survival rates for laryngeal and hypopharyngeal cancer in the United States, based on how far the cancer has spread. The SEER database, however, does not group cancers using AJCC TNM stages for laryngeal or hypopharyngeal cancer. Instead, it groups cancers into localized, regional, and distant stages:
- Localized: There is no sign that the cancer has spread outside of the larynx or hypopharynx.
- Regional: The cancer has spread outside the larynx or hypopharynx to nearby structures or lymph nodes.
- Distant: The cancer has spread to distant parts of the body, such as the lungs.
