Ovarian Cancer: Risks and Symptoms

T4 at physiologic concentrations and T3 at supraphysiologic concentrations increase abundance of proliferating cell nuclear antigen and ERK1/2 activation, markers of cell proliferation, in small cell and non-small cells lung cancer models . Interestingly, thyroid hormones led to phosphorylation of ER, while an ER antagonist blocked T4 induced PCNA expression, ERK1/2 activation and ER phosphorylation. This suggests, as demonstrated in breast cancer cells, that thyroid hormone mitogenic effects mediated via the plasma membrane may involve an ER dependent pathway. Tetrac, as well as pharmacologic inhibition of the MAPK pathway, blocked lung cancer cell proliferation in response to thyroid hormones . Moreover, in human non-small cell lung cancer cells, T4 at physiological concentrations enhanced internalization and nuclear translocation of the integrin v monomer. v monomer then binds inside the cell nucleus promoters of central cancer-related genes, such as ER, cyclooxygenase-2, hypoxia-inducible factor-1 , and thyroid hormone receptor 1 .

Considerations When Conducting Genetic Testing

Indications for genetic testing

Several professional organizations and expert panels including the American Society of Clinical Oncology, the National Comprehensive Cancer Network , the American Society of Human Genetics, the American College of Medical Genetics and Genomics, the National Society of Genetic Counselors, the U.S. Preventive Services Task Force, and the Society of Gynecologic Oncologists have developed clinical criteria and practice guidelines that can be helpful to health care providers in identifying individuals who may have a BRCA1 or BRCA2 pathogenic variant.

Other studies have also found that the NCCN criteria have good sensitivity when predicting BRCA1/BRCA2 variants; however, less is known about many other genes. For example, one study showed that the NCCN criteria were able to detect 88.9% of the BRCA1/BRCA2 pathogenic variant carriers and others have found that, if more than one NCCN criterion is met, then the positive predictive value does pass the 10% threshold .

How Does The Thyroid Impact My Periods

You might be wondering what a small gland in your neck has to do with your periods? A lot. Your thyroid releases hormones that react with other hormones, even the ones in your ovaries.;

If your thyroid is underactive, also known as hypothyroidism, and not producing enough hormones, it can impact your period in a couple of different ways.

First, it can prevent your ovaries from producing progesterone which is a hormone that can decrease your flow. Secondly, underactive thyroids can also reduce your ability to coagulate or stop bleeding. Without the ability to control your flow during each menstrual cycle, youre at risk for developing heavy, uncomfortable, and inconvenient periods every month.;

The good news about having a thyroid issue is that its generally easy to diagnose and treat.

Is Your Thyroid Killing You Breast Cancer

I wrote this article almost 5 years ago at;the very start of this blog Hypothyroid Mom. I have;not;reshared it;again in all these years.

Why?

The C word is the scariest word I know and I know it is for so many of my readers. I lost my father, father-in-law, and 16-year-old nephew to cancer. I know the seriousness of this word and I dont use it lightly. At the time I wrote this article I had discovered research showing an association between hypothyroidism and breast cancer. I;knew more research needed to be done and quite honestly I did not want to scare myself or anyone else with what I had discovered.

A few weeks ago, however, while researching for another article that I am currently writing for Hypothyroid Mom, I stumbled across more recent studies that add fuel to this ongoing controversy that truly;left me numb. Ive thought about these studies so many times since and now its time to update this article and reshare it.

This;not;to scare us but to push us to be the fiercest advocates for ourselves. I also want to shake the medical community that continues to diagnose and treat hypothyroidism with a protocol that fails millions of us and shout,

HEY MEDICAL WORLD, WAKE THE HELL UP.

Thyroid Cancer: The Symptoms Causes And Treatments

Spread the Word! Testicular Cancer Infographic for April ...

Thyroid cancer is one of the most common forms of cancer. The thyroid is a small gland in the neck that sits below the larynx and near the trachea. When overactive cells start growing, it causes a malignant tumor that can destroy nearby tissue and metastasis to other parts of the body. In 2020, its estimated that nearly 53,000 Americans will be diagnosed with thyroid cancer. And surprisingly, its easy to overlook symptoms because they can be commonly associated with other conditions.

Recognizing the symptoms of thyroid cancer is the first step towards treatment and recovery. This can also prevent the cancer from spreading and infecting other parts of the body.

Here is what you need to know about thyroid cancer.

Causes: Why Hypothyroidism Happens

The thyroid gland produces two main hormones: thyroxine and triiodothyronine . When someone has hypothyroidism, their thyroid gland doesnât produce enough of these hormones. This can happen for a few different reasons:

*Iodine deficiency *

In some places where malnutrition or iodine-deficient soil exists, people are not able to get enough iodine in their diets. Without enough iodine in the diet, people can develop an iodine deficiency. This can cause hypothyroidism and a goiter to develop .

Autoimmune disease

In places where people have access to enough iodine in their diet, hypothyroidism is most often caused by an autoimmune disease called Hashimotos disease . This disease causes a personâs immune system to attack their thyroid gland, preventing it from working properly . Itâs not yet clear what causes this to happen.

Physical or medical damage to the thyroid

Hypothyroidism can also develop when the thyroid is physically damaged. This can happen when someone is receiving treatment for hyperthyroidism or having surgery or radiation around the area of the thyroid . Medication, such as lithium, can also cause hypothyroidism as a side effect .

    What Is Postpartum Thyroiditis

    Postpartum thyroiditis, or inflammation of the thyroid after giving birth, affects 10% of women. It often goes undiagnosed because symptoms are much like the baby blues that may follow delivery. Women with postpartum thyroiditis may feel very tired and moody.

    Postpartum thyroiditis typically happens in two phases, though not everyone with the condition goes through both phases:

    • The first phase starts 1 to 4 months after giving birth and typically last 1 to 2 months. In this phase, you may have because the damaged thyroid leaks thyroid hormones out into the bloodstream.
    • The second phase starts about 4 to 8 months after delivery and lasts 6 to 12 months. In this phase, you may have because the thyroid has lost most of its hormones or because the immune attack is over and the thyroid may recover later.

    Why Get Checked For Hyperthyroidism

    Talcum Powder Cause Ovarian Cancer

    Thyroid disorders are manageable once theyâve been diagnosed, but it can be difficult to spot their symptoms. Left untreated, symptoms can worsen and impact a personâs quality of life. Untreated hyperthyroidism can lead to brittle bones, heart problems, and eye problems . Rarely, people with hyperthyroidism may experience a sudden and serious intensification of symptoms called a thyrotoxic crisis, also known as a hyperthyroid storm . Thyrotoxic crisis is considered a medical emergency that should be treated immediately.

    Pregnancy with untreated hyperthyroidism can have negative outcomes for both the pregnant parent and child, including low birth weight, preterm delivery, and pregnancy-induced high blood pressure .

    Talcum Powder And Asbestos

    Habitual use of talcum powder on the genital area may increase the risk for ovarian cancer, but the evidence is not strong. A study at Harvard Medical School found that using talc this way doubled the risk, but other studies found no increased risk. Some researchers believe that talc may be carcinogenic because it contains particles of asbestos, a known carcinogen. Its been shown that rates of ovarian cancer are higher than normal in women whose jobs expose them to asbestos.

    How Hypothyroidism Is Diagnosed

    Hypothyroidism can be diagnosed in two forms: subclinical hypothyroidism and hypothyroidism.

    People with subclinical hypothyroidism do not usually have any of the typical symptoms. On laboratory blood tests their thyroid hormones are shown to be within normal ranges . Subclinical hypothyroidism is diagnosed through laboratory tests, which indicate that the thyroid stimulating hormone is above the normal range . Subclinical hypothyroidism is more common than typical hypothyroidism . Some people with subclinical hypothyroidism can progress to develop hypothyroidism.

    In comparison, people diagnosed with hypothyroidism have clear underfunctioning of their thyroid gland and often have typical symptoms. The blood laboratory results of someone with hypothyroidism have low levels of thyroid hormones and high levels of thyroid stimulating hormone .

    A healthcare provider will probably ask questions about symptoms and medical, family, and menstrual history. In particular, they will want to hear about possible miscarriages or trouble getting pregnant. They will likely perform a physical exam. If the healthcare provider thinks a thyroid disorder might be present, they will likely run some blood tests to measure levels of thyroid hormones. In some cases, an ultrasound of the thyroid gland will be performed.

    Can Hyperparathyroidism And Thyroid Cancer Occur At The Same Time

    Research indicates patients may simultaneously experience HPT and thyroid cancer.

    Inone study, researchers performed a retrospective review of patients who underwent surgery for HPT between 1975 and 1996. Researchers found that 21 patients had a papillary carcinoma, and one patient had a follicular carcinoma. They also indicated that patients with HPT and a history of head and neck irradiation faced a greater risk of thyroid carcinoma than others.

    Comparatively,another study was used to examine four patients dealing with primary HPT . The study indicated PHPT patients may face an increased risk of thyroid cancer in contrast to others. Yet, false-positive results of thyroid cancer were reported in around 10% of PHPT cases. To alleviate this issue, researchers suggested PHPT patients undergo an ultrasound to examine the thyroid gland. They also stated that surgical flexibility is key, and surgeons should get a thyroid nodule sample as part of their efforts to properly diagnose and treat PHPT and thyroid cancer.

    Children who have a parent, or brother or sister, who had retinoblastoma should be checked for retinoblastoma. They usually have screening from birth to the age of 3 years. This involves regular eye examinations under a general anaesthetic. How often and how long a child has screening for depends on their level of risk.;

    Some children might also have a blood test for the RB1 gene. This is only possible if the family member who has had retinoblastoma can be tested first.;;

    Renal Cancer Cell Models

    Renal cancer is associated with multiple aberrances of thyroid hormone signaling pathway. These include mutations and altered expression of thyroid hormone receptors, decreased intratumoral concentrations of T3, as well lowered expression and disturbed alternative splicing of type 1 iodothyronine deiodinase . In contrast to normal kidney cells, which decrease proliferation in response to T3, divisions of renal cancer cell lines are stimulated by TH . These different T3 effects are the result of distinct, cell type specific regulation of genes that control cell cycle progression. In renal cancer cells T3 attenuates expressions of E2F4, p107, and p130, while in healthy kidney cells the expression of p107 is stimulated by T3. p107 and p130 are proteins of the retinoblastoma family which enable binding of E2F4 and E2F5 to form CERC . During G1 phase, CERC interacts with and negatively affects the activity of promoter of CCNE1, encoding cyclin E1, thus repressing proliferation . In consequence of these disparate effects on gene expression, T3 accelerates cell cycle progression in renal cancer cells, triggering progression to S phase. In contrast, in normal kidney cells, cell cycle progression is attenuated by T3 . These pro-proliferative T3 effects on renal cancer cells were confirmed by an independent study .

    Goff and coworkers from the University of Washington reported results in JAMA of a prospective case-control study of 128 women undergoing surgery for a pelvic mass and 1,709 women who visited 2 primary care clinics and completed an anonymous survey on the severity of their symptoms between July 2001 and January 2002 . The objective of the study was to compare the frequency, severity, and duration of symptoms between women with ovarian cancer and women presenting to primary care clinics. The primary outcome measure was differences in self-reported symptoms between these groups of women. Compared to control patients , ovarian cancer patients were 7.4 times more likely to report increased abdominal size, 3.6 times more likely to complain of bloating, 2.5 times more likely to have urinary urgency, and 2.2 times more likely to have pelvic pain. All of these differences were statistically significant. In addition, these investigators found that the combination of bloating, increased abdominal size, and urinary symptoms was found in 43% of women with ovarian cancer but only 8% of women presenting to primary care clinics.

    Its All About The Thyroid

    The thyroid is a butterfly-shaped gland at the base of the neck that produces thyroid hormone. Thyroid hormone affects almost every cell in the body and has many crucial functions, like controlling metabolism, heart rate, and body temperature.

    Some people have hyperthyroidism, or an overactive thyroid, in which the thyroid gland produces too much thyroid hormone. This can cause weight loss, thinning hair, sweating, anxiety, and a rapid heartbeat. Women are five to 10 times more likely than men to develop an overactive thyroid.

    Hypothyroidism, or an underactive thyroid develops when the thyroid gland does not produce enough thyroid hormone. Symptoms of an underactive thyroid include weight gain, fatigue, constipation, depression, dry hair, and a slow heart rate. Like hyperthyroidism, its also more common in women than in men.

    In an effort to determine whether having an overactive or underactive thyroid affects a womans risk of breast cancer, researchers looked at a large group of women in Denmark diagnosed with thyroid disease between 1978 and 2013. More than 60,000 of the study participants had an underactive thyroid, and more than 80,000 had an overactive thyroid. They followed the patients for five to seven years and found that those with an overactive thyroid had a slightly increased risk of breast cancer an 11% higher risk, to be specific. However, women with an underactive thyroid had a 6% drop in their breast cancer risk.
