Blood test that can detect ovarian cancer 'may save lives and stop women having unnecessary surgery' to spot the killer disease

A blood test that can detect ovarian cancer could spare thousands of women from unnecessary surgery, researchers hope.

• Women with ovarian cysts endure surgery to help doctors spot any tumours 
• For every one cancer that is detected, five women are operated on
• Blood test identifies 11 proteins that are higher in women with ovarian cancer

Women with ovarian cysts or cancer symptoms, such as bloating, are often forced to go under the knife to help doctors spot any tumours.

Researchers claim that for every one cancer case that is detected, five women are operated on, putting them at risk of pain, infection and blood loss. 

The new test, developed by scientists in Sweden, searches the blood for 11 proteins that are higher in women with malignant ovarian masses.

Charities say further trials are needed to confirm the test is accurate, saying it would represent 'a major breakthrough' if it is.

Researchers at Uppsala University, behind the test, hope it could one day be used as part of a routine ovarian cancer screening programme. 

Early detection of ovarian cancer is considered to be the 'holy grail', and scientists around the world are trying to find an effective method.

'Our results are promising enough to consider screening for early discovery of ovarian cancer,' lead author Professor Ulf Gyllensten said.

'In Sweden, we have long experience of screening for cervical cancer. I see great prospects of developing a strategy for screening for ovarian cancer as well.'

He said such a programme could 'save lives and minimise the need for surgery to rule out cancer'.

The blood test was tried on plasma samples taken from 90 women with the disease and 79 without. It was then repeated three times.

It compared circulating levels of 593 proteins between women with ovarian cancer, benign tumours or no sign of the disease. 

Results found the test distinguished between women with the disease and those without up to 93 per cent of the time.

The researchers, writing in the journal Communications Biology, found quantities of 11 proteins were higher in patients with cancer. 

Results revealed it had a sensitivity of 85 per cent, which measures the probability of a test identifying cases.

It also had a specificity, which describes a test's ability to pick up non-cases, of 93 per cent.   

Ovarian cancer affects 7,300 new women every year in the UK, Target Ovarian Cancer statistics show.

And in the US, around 22,530 women are expected to be diagnosed in 2019, according to the American Cancer Society (ACS). 

Ovarian cancer's vague symptoms, such as feeling full quickly, are difficult to diagnose and mean the disease is often only spotted once it is advanced.

WHY OVARIAN CANCER IS CALLED A 'SILENT KILLER' 

About 80 percent of ovarian cancer cases are diagnosed in the advanced stages of the disease.

At the time of diagnosis, 60 percent of ovarian cancers will have already spread to other parts of the body, bringing the five-year survival rate down to 30 percent from 90 percent in the earliest stage.  

It's diagnosed so late because its location in the pelvis, according to Dr Ronny Drapkin, an associate professor at the University of Pennsylvania, who's been studying the disease for more than two decades.

'The pelvis is like a bowl, so a tumor there can grow quite large before it actually becomes noticeable,' Dr Drapkin told Daily Mail Online.

The first symptoms to arise with ovarian cancer are gastrointestinal because tumors can start to press upward.

When a patient complains of gastrointestinal discomfort, doctors are more likely to focus on diet change and other causes than suggest an ovarian cancer screening.

Dr Drapkin said it's usually not until after a patient endures persistent gastrointestinal symptoms that they will receive a screening that reveals the cancer.

'Ovarian cancer is often said to be a silent killer because it doesn't have early symptoms, when in fact it does have symptoms, they're just very general and could be caused by other things,' he said.

'One of the things I tell women is that nobody knows your body as well as you do. If you feel something isn't right, something's probably not right.'

Only 30 to 40 per cent of patients survive five years after treatment, according to statistics.

Unlike breast and cervical, ovarian cancer is not screened for in the UK because there isn't a test that reliably spots them at an early stage.

Women who are suspected to have the disease are therefore forced to undergo an ultrasound scan to check for any abnormalities. 

They may then be sent for 'surgical sampling'. As well as this procedure being invasive, over-diagnosis is high. 

One study found out a group of women diagnosed via surgery, just 21-to-30 per cent had ovarian cancer. The rest had benign tumours or borderline masses.  

Study author Professor Karin Sundfeldt said: 'We need to develop more accurate pre-surgery diagnostics. 

'To detect one cancer, we operate on up to five women - yet this is currently the best option when abnormalities are detected by ultrasound and cancer is suspected.

'There is a great need for a simple blood test that could identify women who do not need surgery.' 

Alexandra Holden, director of communications at Target Ovarian Cancer, added: 'Early detection of ovarian cancer is the holy grail.

'Research into new biomarkers shows great promise and we look forward to a future where more women are diagnosed at the earliest possible stage.

'If borne out by future research, this would represent a major breakthrough.' The researchers admitted further trials are needed.

It is not the only blood test that is being trialled for spotting ovarian cancer early.  

One already being used with looks for the chemical CA125, which is given off by cancer cells that circulate in the bloodstream. 

However, not everyone with ovarian cancer has elevated CA125, meaning it is not a reliable candidate for a screening programme. 

Another approach involves putting an ultrasound probe into the vagina to give medics a better picture of the ovaries. 

But it can be difficult to tell whether an ovary has a tumour or just a harmless cyst using this method.

For both screening methods, there is 'no clear evidence these pick up cancers early and save lives', according to Cancer Research UK. 

WHAT ARE THE SYMPTOMS OF OVARIAN CANCER?

The symptoms of ovarian cancer can be difficult to recognise, particularly early on.

They're often the same as symptoms of less serious conditions, such as irritable bowel syndrome (IBS) or pre-menstrual syndrome (PMS). 

The most common symptoms of ovarian cancer are:

• Feeling constantly bloated
• A swollen tummy
• Discomfort in your tummy or pelvic area
• Feeling full quickly when eating, or loss of appetite
• Needing to pee more often or more urgently than normal

Other symptoms can include:

• Persistent indigestion or nausea
• Pain during sex
• A change in your bowel habits
• Back pain
• Vaginal bleeding – particularly bleeding after the menopause
• Feeling tired all the time
• Unintentional weight loss

When to see your GP

See your GP if:

• You've been feeling bloated most days for the last three weeks
• You have other symptoms of ovarian cancer that won't go away – especially if you're over 50 or have a family history of ovarian or breast cancer, as you may be at a higher risk

It's unlikely you have cancer, but it's best to check. Your GP can do some simple tests.

Maca Benefits for Various Health Conditions

Maca Benefits: A Super Herb That’s Been Used to Heal a Variety of Health Conditions

The Peruvian herb, maca, is not only one of the best known natural aphrodisiacs, but is also highly beneficial to your health…

Maca (Lepidium meyenii), a hearty root vegetable belonging to the radish family, grows in the high Andean plateaus of Peru. It has gained the reputation of being a super herb in recent years, and the benefits of maca have been used for over 2,000 years to heal a variety of health conditions.

It is best known for its ability to enhance fertility and libido. Even before the Spanish conquistadors colonized the Inca Empire in the 16th century, the Incas had already been using maca for a multitude of health reasons.

In 1960, Gloria Chacon de Popovici, Ph.D., a Peruvian biologist, isolated the 4 alkaloids responsible for maca’s reputed positive effect on hormonal issues such as hot flashes, fatigue, mood swings, memory loss — and even male impotence.

Maca’s reputation for restoring physical strength and libido has caused many a South American to nickname it “Spanish Viagra.” [Note: Maca bears no resemblance to, nor does it have any association with, the trademarked drug after which it is nicknamed.]

Throughout its long history of therapeutic use, maca has been shown to provide the following health benefits:

• It is a powerful natural aphrodisiac and libido-enhancer that also promotes reproductive health. The journal Plant Science reported that when maca was used in a reproductive health study, it increased the sperm count in male test subjects in just 2 weeks!
• It alleviates the symptoms of menopause and PMS. Indian women use it to treat menopausal symptoms, and Peruvian women have used it for years to encourage fertility and treat pre- and post-menstrual problems. Maca’s calcium, silica and magnesium content helps prevent bone loss that may accompany menopause-induced osteoporosis.
• It boosts energy levels and aids in athletic performance.
• Maca contains glucosinolate and fibers that help prevent certain forms of cancer. Its fatty acid content helps strengthen the body’s immune system, thereby enabling to body to fight cancer.
• It promotes mental clarity. Researchers have given maca to students before tests to improve students’ test scores.
• Maca is an adaptogen. As such, it increases the body’s resistance to stress, trauma, anxiety and fatigue.
• It is rich in antioxidants, fatty acids, vitamins, minerals, amino acids and other nutrients that support optimum health and longevity.
• Because of its high iron content, it has been shown to be beneficial for those who suffer from anemia.
• Maca contains terpenoids and saponins which give it the ability to relieve pain, act as expectorant, sedative and analgesic — and even lower cholesterol levels.

In Peru, maca is usually eaten like a potato, boiled and used in pudding, jams and drinks. Everywhere else, maca is more readily available at health food stores and from online retailers as a powder that can be conveniently added to food or drinks. Maca is also available in the form of capsules or liquid extract, both of which can be self-administered as dietary supplements.

Amazing Benefits of Bananas

Health Benefits of bananas

While bananas have always been associated with monkeys, and apples with doctors, the truth is that they are both just as beneficial to one’s health. These are benefits that can change one’s life whether they are woman, child or man, and so here is a list of benefits that pertain not only to the physical aspect of one’s health but also the mental as well:

Benefit #1: Minor Burns and wounds

If one has wounds that are due to burns that are minor in nature, this fruit can help relieve the pain that these wounds cause while healing. The best way to do this is to mash the banana and use a paper towel or cloth to wrap it up and then place it on the affected area.

Benefit #2: Energy

Since bananas have three sugars such as sucrose, fructose and glucose, eating this fruit will ensure that these sugars will give your body a lot of energy.

Benefit #3: PMS

As this fruit contains high levels of vitamin B6, this regulates the blood sugar levels in one’s body, women who are normally moody while experiencing pains as well during PMS can also benefit from eating bananas.

Benefit #4: Depression

Bananas have been known to give one a natural high due to substances such as tryptophan, norepinephrine, serotonin and vitamin B. Most of these nutrients help to calm one’s mind and relax, thus working as an excellent way to combat depression.

Benefit #5: Blood Pressure

It is well-known that high levels of sodium can cause conditions pertaining to high blood pressure as well as heart disease as well, but since bananas have the nutrient known as potassium, this helps to lower blood pressure as well as reduce the risk of one getting heart disease as well.

Benefit #6: Ulcers

Bananas are considered to be one of the few foods that an ulcer patient can eat without suffering pain, and the reason for this is lowers the level of acidity in the gastric juices that are present in one’s stomach as well as build a protective coating inside the stomach.
