Cancer, which is a common disease nowadays is mainly caused due to rapid growth of cancer cells inside our body. There are various types of cancers which are present such as Breast Cancer, Lung Cancer, Pancreatic Cancer etc.
Skin Cancer(Melanoma),which is mostly curable, can become deadly if not detected at an early early stage. Hence, it is important to detect which one is malignant and which one is benign.
The model proposed here , is capable to classify images based on Convolutional Neural Networks and can eventually yield good results.

The dataset is available on Kaggle which was given by Claudio Fanconi. Basically ,the data is splitted into 2 types, test and train data. There were approximately 2637 images in training set and 660 in testing set. The images provided in the set were mostly quite clear and well formatted.
The training and test set were already present in the dataset. However, the validation set was missing. So, we took 25% of the training data ,and converted it into validation data.
Dummy Data: This data will be useful for model’s prediction, which consist of 5 images
By definition, Image Processing is a method to perform some operations on an image ,in order to get an enhanced image or to extract some useful information from it. It is a type of signal processing in which input is an image and output may be image or characteristics/features associated with that image.
Since ,the image size has a maximum pixel of 255 ,i.e it has a range of [0,255],but it becomes tough for the model to process such high pixel so we need to rescale it before feeding to model.
Model Training :
In this CNN Model, we have used 6 layers of “ReLU” and the last layer is of “Softmax”.
The model performed well on the test and training both. It has able to yield an accuracy of approximately 82 % on train and 77% on test.
