Transcript of Cancer
Symptoms and Treatments
Cancer Council (2015a) estimates 128,000 new cases of cancer will be diagnosed in Australia this year. Some of the most common cancers affecting Australians today include
1. Bowel (men and women
2. Breast (men & women)
3. Lung (men &women)
Several well known cancer websites (Australian Government Department of Health, 2015; Australian Government, 2015; Bowel Cancer Australia, 2015) describe the main screening and diagnostic methods of bowel cancer as:
An internal examination of the rectum, anus and colon – this may include a sigmoidoscopy or colonoscopy by a doctor or specialist
A blood test to check for anaemia
Imaging of the bowel, which may include barium enema, computed tomography (CT) scan or magnetic resonance imaging (MRI)
Taking a sample of tissue (biopsy) from the bowel wall for examination under a microscope
The statistics (Cancer Council, 2015d)
Cancer Council (2015a) describes bowel cancer (also known as colorectal cancer) , as cancer in any part of the colon or rectum.
Bowel cancer is a malignant growth (uncontrolled multiplication of cells) that develops most commonly in the lining of the large bowel and develop from tiny growths (polyps) into large cancerous bodies.
The National Bowel Cancer Screening Program (NBCSP) invites men and women 50+ to participate in a free screening program at home. According to Bowel Cancer Australia (2015), this screening program involves the self use of a screening kit called a Faecal Immunochemical Test (FIT) also known as an immunochemical Faecal Occult Blood Test (iFOBT) which can detect small amounts of blood in bowel movements. The test involves placing a small sample of toilet water or stool on the kit sample area and sending to a laboratory for evaluation.
According to research by Cole et al (2013), due to the NBCSP several cancers were being detected at an earlier stage which would reduce the mortality rate showing evidence the screening program is working and beneficial. Anderson and Shaw (2014) reviewed several technologies to detect polyps and cancers which include the following below which have ranges in effectiveness in detecting polyps as shown below
Faecal DNA tests to find cancer cells (51.6%)
CT Colonography to see polyps (90%)
Colon Capsule Endoscopy to see polyps (69%)
Faecal Immunochemical Test to detect blood in stool (79%)
PROGRESSION FROM POLYP TO CANCER
The Statistics (Cancer Council, 2015e)
The Australian Institute of Health and Welfare & Cancer Australia [AIHW], (2012) suggest a combination of earlier diagnosis associated with screening and advances in treatments are improving the survival rates for breast cancer each year.
No other technology has been proven as a screening test to reduce deaths from breast cancer.
Breast screening involves mammography (taking X-ray pictures of the breast) performed radiographers.(Department of Health for the Australian Government [DoH], 2015)
Watch this video about having a mammogram from Breast Screen Australia
Breast Screen Australia recommends becoming breast aware as opposed to examining your breasts every month (Department of Health for the Australian Government [DoH], 2015).
Being breast aware means knowing what is normal for your breasts and which changes to look out for, improving the likelihood of noticing anything unusual more quickly.
Generally the sooner breast cancer is diagnosed and treated, the better the prognosis (Pennery, Speechley, & Rosenfield, 2009).
A new lump or lumpiness in your breasts, especially if it is in only one breast
Changes to the size or shape of your breast or nipple
A discharge from your nipple without squeezing
New redness, dimpling or puckered skin on the breast
Pain that does not go away
The Department of Health for the Australian Government [DoH] (2015) suggest things you should look out for include
(National Breast Cancer Foundation, 2012)
you should check your breasts...
(BreastScreen Victoria, 2012)
Ongoing studies are looking at lifestyle factors such as exercise, weight gain or loss, diet and other habits that influence breast cancer risk (Cancer Council, 2015b).
Has been touted as the way of the future (Blumenschein, 2014), as a way to take advantage of gene changes in cells that cause cancer.
A slightly radioactive tracer is injected into a vein, attaching to breast cancer cells and is detected by a special camera. This technique is still being studied to see if it will be useful in finding breast cancers. Some radiologists believe it may helpful in looking at suspicious areas found by regular mammograms, almost as accurate as more expensive magnetic resonance imaging (MRI) scans (American Cancer Society, 2015).
Molecular breast imaging (Scintimammography)
Targeted molecular therapy
Breast cancer is a disease in which abnormal cells in the breast tissues multiply and form an invasive (or malignant) tumour (Australian Institute of Health and Welfare & Cancer Australia (2012).
The tumours may damage and invade the surrounding tissue and spread to other parts of the body through the lymphatic or vascular systems.
If the spread of breast tumours are not treated or controlled, they can result in death. Tumours that are non life-threatening are called benign tumours (Australian Institute of Health & Welfare & Cancer Australia, 2012).
The video below from Bowel Cancer Australia (2011) gives a good overview of the causes, symptoms and treatment available for bowel cancer
This presentation aims to give insight into each of these cancers including screening techniques, treatments and recent advances in order to provide general knowledge of the above mentioned cancers

(Mesothelioma Stages, 2014)
Small Cell Lung Cancer – SCLC
Develops as malignant tumours in the tissue of the lungs.
In Australia it rates as the 5th most diagnosed cancer.
Predominantly diagnosed at ages 65 to 79. There are two main types of lung cancer:
Non Small Cell Lung Cancer - NSCLC
Squamous cell carcinoma
Large cell carcinoma
Small cell carcinoma
Mixed small cell / large cell carcinoma
(Cancer Council, 2015c)
Mesothelioma or Lung Cancer?
Mesothelioma is a condition that affects the plural membranes around lungs
This occurs in the lining of the abdomen or around the heart which is not the same as lung cancer, and is always caused by exposure to asbestos (Cancer Council, 2015c).
(Community Connect to Research, 2012)
New dry cough or change in a chronic cough
Chest pain or breathlessness
Persistent illness of pneumonia or bronchitis
Coughing or spitting up blood
Other indicators could be:
Fatigue, weight loss, hoarseness, wheezing, difficulty swallowing, abdominal or joint pain.
(Cancer Council, 2015c)
Unlike other cancers there are no current screening Programs in Australia for early detection of Lung Cancer. Research has been undertaken into the cost effectiveness for potential of future screening but points to the cessation of smoking to be the most significant factor in the reduction of Lung Cancer. (Marshall & Fong, 2013)
Cancer Council Australia recommend healthy lifestyle choices, highlighting
reducing exposure to toxic elements such as nickel, chrome or coal gas and limiting exposure to radiation and diesel fumes
To reduce risk of Lung Cancer, the Cancer Council (2015c) advise annual check ups which will assist your GP in observing any changes to your health and following up on symptoms of Lung Cancer . The quit smoking campaigns have had the greatest impact upon the reduction of lung cancers diagnosed.
Treatment and Recent Advances
Tests to diagnose lung cancer:
A Chest X ray detects tumours one centimetre or larger.
A CT scan uses x-ray beams, it takes three dimensional images, can detect smaller tumours and enlarged lymph nodes. This may include injection with iodine for a clearer picture.
Bronchoscopy – (biopsy) allows the Doctor to view the bronchi and take a small sample of lung tissue.
PET (position emission tomography) used for diagnosis when biopsy is not possible or inconclusive.
Sputum Cytology is the examination of phlegm or mucus.
If cancer is present, recommended treatment may be surgery for partial removal of the tumour affected lung, radiotherapy and chemotherapy for the shrinkage of tumours. (National Health and Medical Research Council, 2004)
Future advances are hoped for detection methods in both breath and blood with samples and experimentation under current research (Marshall & Fong, 2013). Easier screening options are under constant discussion for future consideration.
(Cancer Council, 2015g)
Cancer is affecting the lives of Australians each day and through the medical research and constant advances over 66% of people diagnosed with cancer in Australia are still alive five years after diagnosis (Cancer Council, 2015). The survival rate for many common cancers has increased by 30 per cent in the past two decades (Cancer Council, 2015), which can be largely attributed to the ongoing awareness and information of risk factors and things to avoid, becoming available to the wider public. Being aware of screening tests available, ensures Australians can continue to be educated in how to deal with this silent killer.

Breast screening is recommended for women once they turn 50, or have been recommended by their doctor. Screening should then be repeated every 2 years. Research shows that regular screening has the greatest benefit for women within this age group (Cancer Council, 2015b).
Uncontrollable multiplication of cells lining the colon that turns into a large growth (polyps) which grows rapidly in size eventually breaks through the bowel lining and enters the blood stream
Blood in stool
Change in bowel habits
Unintended weight loss
Depending on the severity of the cancer, doctors may recommend and of the following
Surgery to remove all damaged parts of the bowel
Surgery to remove polyps
(Bowel Cancer Australia, 2011)
Bowel Cancer Australia (2015) illustrates how polyps start small and may increase in size becoming cancerous. Not all polyps are cancerous, however if they become large enough they can puncture the lining of the bowel and enter the blood stream. Doctors are particularly worried about these types of polyps and recommend their removal prior to this occurring.
