Deadly link between alcohol and breast cancer is 'ignored by middle-aged women who are MOST at risk of developing the disease'

  • Breast cancer is the most commonly diagnosed form of the disease in Australia
  • Women in their 40s, 50s and 60s still consume large amounts of alcohol 
  • They accept alcohol can cause weight gain and relationship breakdowns
Middle-aged women are not getting the message about the proven link between alcohol and breast cancer, new research suggests.
Females in their 40s, 50s and 60s are still consuming large mounts of wine, beer and spirits despite rates of the disease rising in their age brackets.
Data from Flinders University in Adelaide shows a disconnect between the cause and effect, despite public awareness campaigns. 
But they accept alcohol can result in weight gain and lead to relationship breakdowns.

Study lead author Dr Emma Miller said: There is a low level of awareness about the established link between alcohol and breast cancer, and some confusion about the risk given the community perception that not all drinkers get breast cancer.
'So it's really important to understand the patterns and drivers behind drinking behaviour in order to develop policies and interventions that might reduce the increasing burden on the women and our health system.'
Breast cancer is the most commonly diagnosed cancer in Australia, accounting for more than 13 per cent of all new forms of the disease and 28 per cent of all malignant tumours diagnosed in women.
As part of the study, 35 South Australian women - aged between 45 and 64 - who have never been diagnosed with cancer, were interviewed about their alcohol consumption, education level and perceived risk of breast cancer.  
Dr Miller claims the findings suggest targeted messages that address short-term risks will have the greatest impact. 
'Alcohol is firmly entrenched in the fabric of Australian society, providing pleasure and defining the major events in most of our lives,' she said.
'Raising awareness of alcohol-related cancer risk, despite the importance of this, will not be sufficient to counter patterns of consumption.'

Dr Miller added: 'We all want to hear good news about drinking, such as small amounts of red wine may be good for cardiovascular disease, which is a message that's promoted by the alcohol industry.
'In contrast, information that alcohol is linked to breast cancer is actively suppressed by the industry presumably in order to build the female customer base.
'Our research shows that while more middle aged women are drinking, there are ways of getting the right messages through by focusing on issues important to them.
'For example, younger people are drinking less so we can look into the reasons behind that and utilise them.'

WHAT IS BREAST CANCER, HOW MANY PEOPLE DOES IT STRIKE AND WHAT ARE THE SYMPTOMS?

Breast cancer is one of the most common cancers in the world. Each year in the UK there are more than 55,000 new cases, and the disease claims the lives of 11,500 women. In the US, it strikes 266,000 each year and kills 40,000. But what causes it and how can it be treated?
What is breast cancer?
Breast cancer develops from a cancerous cell which develops in the lining of a duct or lobule in one of the breasts.
When the breast cancer has spread into surrounding breast tissue it is called an 'invasive' breast cancer. Some people are diagnosed with 'carcinoma in situ', where no cancer cells have grown beyond the duct or lobule.
Most cases develop in women over the age of 50 but younger women are sometimes affected. Breast cancer can develop in men though this is rare.
The cancerous cells are graded from stage one, which means a slow growth, up to stage four, which is the most aggressive.
What causes breast cancer?
A cancerous tumour starts from one abnormal cell. The exact reason why a cell becomes cancerous is unclear. It is thought that something damages or alters certain genes in the cell. This makes the cell abnormal and multiply 'out of control'.
Although breast cancer can develop for no apparent reason, there are some risk factors that can increase the chance of developing breast cancer, such as genetics.
What are the symptoms of breast cancer?
The usual first symptom is a painless lump in the breast, although most breast lumps are not cancerous and are fluid filled cysts, which are benign. 
The first place that breast cancer usually spreads to is the lymph nodes in the armpit. If this occurs you will develop a swelling or lump in an armpit.
How is breast cancer diagnosed?
  • Initial assessment: A doctor examines the breasts and armpits. They may do tests such as a mammography, a special x-ray of the breast tissue which can indicate the possibility of tumours.
  • Biopsy: A biopsy is when a small sample of tissue is removed from a part of the body. The sample is then examined under the microscope to look for abnormal cells. The sample can confirm or rule out cancer.
If you are confirmed to have breast cancer, further tests may be needed to assess if it has spread. For example, blood tests, an ultrasound scan of the liver or a chest x-ray.
How is breast cancer treated?
Treatment options which may be considered include surgery, chemotherapy, radiotherapy and hormone treatment. Often a combination of two or more of these treatments are used.
  • Surgery: Breast-conserving surgery or the removal of the affected breast depending on the size of the tumour.
  • Radiotherapy: A treatment which uses high energy beams of radiation focussed on cancerous tissue. This kills cancer cells, or stops cancer cells from multiplying. It is mainly used in addition to surgery.
  • Chemotherapy: A treatment of cancer by using anti-cancer drugs which kill cancer cells, or stop them from multiplying
  • Hormone treatments: Some types of breast cancer are affected by the 'female' hormone oestrogen, which can stimulate the cancer cells to divide and multiply. Treatments which reduce the level of these hormones, or prevent them from working, are commonly used in people with breast cancer.
How successful is treatment?
The outlook is best in those who are diagnosed when the cancer is still small, and has not spread. Surgical removal of a tumour in an early stage may then give a good chance of cure.
The routine mammography offered to women between the ages of 50 and 70 mean more breast cancers are being diagnosed and treated at an early stage.

Lung cancer could be detected with a BLOOD TEST raising hopes of diagnosing the deadly disease early

  • Lung cancer is officially the world's leading cause of cancer-related deaths 
  • There are 46,400 cases of lung cancer in Britain each year and 35,500 deaths 
  • Only one in 10 patients is still alive five years after diagnosis
  • New test can identify cancer cells by the DNA which they shed as they grow 
Early signs of lung cancer could soon be detected by a simple blood test. 
British researchers have created a new type of screening which can identify early stages of the disease – and even predict where pre-cancerous tumours may develop.
The 'promising' and 'exciting' findings – published in the journal Disease Models and Mechanisms – could be crucial in beating the disease, the experts claim.
Lung cancer is the world's leading cause of cancer-related deaths because it is notoriously difficult to diagnose and often appears later when it's harder to treat.

If a lung tumour is detected early, it may be easily removed in surgery to prevent it spreading to other parts of the body and becoming more difficult to stop.
Dr Mariana Delfino-Machin, programme manager for cancer at the Medical Research Council (MRC), which funded the study, said: 'This is a really promising piece of early-stage research.
'Lung cancer is incredibly difficult to diagnose at the stage where it can be successfully treated, leading to a poor rate of survival.
'Developing early detection strategies to improve survival rates is key, and if this can be achieved using only a blood sample it would greatly benefit patients and the NHS.
'We look forward to the results of the next stages of this research.'
Scientists at the MRC's Toxicology Unit at the University of Cambridge analysed the blood tests of mice with a genetic mutation known as KRAS, which replicates the early signs of lung cancer.

With the help of scientists from the University of Leicester, the researchers discovered the new blood test has the power to measure circulating levels of DNA in the blood, which cancer cells shed as they grow and multiply.
The mice were closely monitored with regular computed tomography (CT) scans and blood tests.

CHEMO MAY CAUSE BREAST CANCER TO SPREAD TO THE LUNGS 

Chemotherapy may cause breast cancer to spread, alarming research suggests.
The commonly prescribed chemo drugs paclitaxel and doxorubicin cause breast tumours to release proteins that then circulate in the blood until they reach the lungs, triggering the disease's onset in a new part of the body.
When scientists - from the Swiss Institute for Experimental Cancer Research - blocked this protein in a lab model, the cancer did not spread. 
They hope their findings - released last December - will help make chemotherapy more effective
It was soon discovered the mice with higher levels of DNA shed from cancer cells in their blood reflected the growth of the tumours seen on the scans.
After the DNA was analysed, it was revealed the KRAS mutation – which causes tumours to develop – was still being detected in the later stages of tumour development.
Study lead author Dr Miguel Martins said: 'This observation is exciting because it suggests that tumour-causing mutations may be detectable in circulating DNA from patients with early-stage cancers or with pre-cancerous tumours.'
But he added more research is needed to examine mice with pre-cancerous tumours in other parts of the body before the test can accurately be applied to humans.
British Lung Foundation's medical director, Nick Hopkinson, said: 'This is an early study in mice, but it is a very interesting area of research. 
'A blood test for lung cancer would be a big step forward as long as it is sensitive and specific so that there are not a lot of false positive or false negative results.
'In the meantime the most important message is, if you’re a smoker, the best thing you can do to lower your cancer risk is to quit smoking. 
'It’s also important not to ignore symptoms like getting out of breath doing things you used to be able to do, or a cough lasting more than few weeks.'

The Phones Emitting the Most Radiation

For most people nowadays, their smartphone is within arm's reach 24 hours a day. It's in their pocket while they're at work, it's in their hand on the train ride home and it's on their bedside table as they go to sleep.

by Martin Armstrong, Feb 4, 2019

 With this level of proximity and usage, many can't quite shake the niggling feeling that they might be risking damage to themselves in the long run. While conclusive longitudinal research on the effects of cell phone radiation is still hard to come by, for those looking to hedge their bets, this infographic shows the phones that emit the most radiation when held to the ear while calling. 

The German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) has a comprehensive database of smartphones - new and old - and the level of radiation they emit. Following the criteria set for this chart (see footnotes), the current smartphone creating the highest level of radiation is the Mi A1 from Chinese vendor Xiaomi. Another Chinese phone is in second place - the OnePlus 5T. In fact, the two companies are represented heavily in this list, with 8 of the top 16 handsets being made by one of them. Premium Apple phones such as the iPhone 7 and the recently released iPhone 8 are also here to be seen, though, as are the latest Pixel handsets from Google.

While there is no universal guideline for a 'safe' level of phone radiation, the German certification for environmental friendliness 'Der Blaue Engel' (Blue Angel) only certifies phones which have a specific absorption rate of less than 0.60 watts per kilogram. All of the phones featured here come in at more than double this benchmark.

Having already revealed the current phones which emit the most radiation, this chart looks at the opposite end of the scale. While conclusive longitudinal research on the effects of cell phone radiation is still hard to come by, for those looking to minimize the risks, this list may be useful. 

The German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) has a comprehensive database of smartphones - new and old - and the level of radiation they emit when held to the ear during a call. Following the criteria set for this chart (see footnotes), the smartphone creating the lowest level of radiation is the Samsung Galaxy Note8 - with a specific absorption rate of 0.17 watts per kilogram. In fact, Samsung handsets feature prominently, with half of the top ten coming from the South Korean company. This contrasts starkly with their major rival Apple. Two iPhones occupy a place in the list of phones which emit the most radiation, compared to none from Samsung.

While there is no universal guideline for a 'safe' level of phone radiation, the German certification for environmental friendliness 'Der Blaue Engel' (Blue Angel) only certifies phones which have a specific absorption rate of less than 0.60 watts per kilogram. All of the phones featured here are well under this benchmark.
